First Look: E-Stim System Connect

Today at EroFame in Hannover, E-Stim Systems introduced a new way to remotely control their top range 2B power box. After basically spending the morning trying the new system out, let me give you a short intro how it works.

First, what do you need? The bottom obviously needs an E-Stim Systems 2b, their Digital Link Interface (already included in their 2B Bonus Pack formally know as the „Pro Pack“ which I reviewed here) and a computer. Currently the software and drivers are available for Windows 10 and macOS. They also supply a Linux software which is currently not yet supported. The top only needs a device connected to the internet with a browser, in this case a Samsung Android tablet.

After installing the drivers and the software, the bottom must connect his computer with the 2b using the USB cable and switch on the box.

After lunching the software and clicking the “Connect” button, it takes a few moments to pair the computer and the power box. This will only work when the computer is connected to the internet. Otherwise the status will stay “Not connected” even though the box and the computer are connected correctly.

Once this is done a 16 digit alpha-numerical code is display. Clicking on the number will copy the connection link which has to be sent to the top.

When clicking to the link, a website with the code already filled in opens. After the top clicks “Connect” the computer client’s indicator switches to “Connected”.

The website on the top’s device now allows to control all basic functions of the 2b like selecting the program, setting the output levels of the two channels or switching from low to high power modus.

Every input given on the website will also be displayed on the 2b’s screen.

Clicking “Stop” sets the output level on both channels to zero. The same happens when changing the program, just like when doing it on the 2b. What I am missing compared to their cold Commander software is a pop-up when (the sub) disconnects the box.

I was impressed how well the software worked on the release date. It is easy and intuitive to use and very responsive. Controlling the box in the same wifi and over mobile internet in the same country almost had no lag. I had a few problems with the desktop client crashing but no major issues. However, E-Stim Systems just announced the new service in a tweet which was to date retweeted twice until now and wrote nothing about it on their website’s landing page. On the 2b product page they still write about their now outdated “Commander” software. So I guess there were not that many people using their server. It remains to be seen how reliable the system works intercontinental or when the server are busy. I will revisit this review in a few months to give you an update.

Until then, I am very impressed by what they have done and it has given the 2b a real advantage towards their competitors. I can already see kinky geeks working on Linux based SBCs with 3G connection to create a mobile remote-controlled e-stim box.

If you are interested in the E-Stim System 2b, you can buy the Bonus Pack which comes with everything needed to connect it to your computer directly from E-Stim Systems for £378 or upgrade your existing 2b power box with the Bonus Pack for £89 or just by the Digital Link Interface for £69. The 2b Power Box and the Accessory Pack are also available at Mr S Leather for $399.95 resp $119.95.

Oxballs Shockballs

The Oxballs Shockball

Vendor: Ballistic Metal

Construction

Like all ball crushers the Shockballs has two plates measuring 189x129mm. The lower one is made out of 6mm thick black acrylic, the top one out of 5.5mm thick clear acrylic. In the upper half, there is a hole in each plate. The lower one of the entire junk, the upper one for just the dick. Both holes are nicely rounded and flawlessly deburred so there will be no unintended pain or injuries. To fit most dick and ball sizes, the Shockballs comes in three hole sizes: 31.7mm & 44.5mm, 38mm & 51mm and 44.5mm & 57.5mm which I have bought.

The plates are connected by a clear acrylic hinge at the top. At the bottom there are two M5 screws for pressing the top plate down on the balls using wings nuts. On the screws there are also nuts as an adjustable compression limiter.

Detail of the Electrodes‘ Upsight with the 4mm Sockets

Below the holes there are two aluminums clamps screwed onto the clear acrylic using three sleeve nuts. The nuts’ round-head are the contact points of the electrodes. To connect the electrode with the power box, there are 4mm holes to fit banana plugs drilled into the bottom of the clamps.

Playing with the Shockballs

The hinge is a blessing and a cruse: Usually with ball crushers your fiddle with two or even three pieces, always risking to pinch some skin. This won’t happen with the Shockballs. But: If the sub already has a full-grown boner it is almost impossible to get the dick through the designated hole so the crusher can’t be closed again. The hinge’s height also limits maximum squeeze to 18mm (and a minimum of 42mm). While that is enough for a strong compression feeling, it won’t cater to the total nut pain pigs who want their balls compressed paper thin.

Detail of the Electrodes‘ Contact Areas

So much for the bad news. The good news is: The toy as an awful lot of fun to play with. While yes, putting it on with a hard dick, especially larger ones, not having to deal with shifting, getting wedged plates made me use the Shockballs way more often than my other ball crushers – even just for crushing. On a more personal note, I also like the industrial look of the brushed aluminum clamps compared to the poles being on the base plate on other e-stim ball crushers which then feature clear top plates. Tough some testees did not like the somewhat obstructed the view on the compressed sack.

The e-stim sensation is generally starts out mostly smooth. But since there are only three contact points it quickly can be turned stingy when the intensity is increased. Since the contact area and mass on both poles is almost identical, the sensation is felt on both poles when connected to one channel of the power box. The most interesting/ deviant stimulation is putting a mass-rich counter pole (everything up from the E-Stim Systems Torpedo Large like the Stuffer or [X]L Black Collection) inside the sub so the stimulation is only felt at the balls. Then choose a program which alternates between the two channels (like HiFreq on the Erostok ET232) so the agony constantly jumps from one side to the other.

Detail of the Screws to Tighten the Crusher

It is general a good idea to put a flexible cockring around junk’s base to keep the balls from retracting back into the body. If a sub has smaller/ tighter balls, I also recommend to stretch his nuts with one of the many flexible cock rings/ ball stretchers from Oxballs. This way they won’t be squeeze through the dick or junk hole (whichever has more slack). If you are really mean, you use the Zapp or Volt to electrify also the ball’s neck.

Conclusion: Nicely looking, easy to handle e-stim ball stretcher – if the dick is soft.

Erostek ET312b

Vendor: Mr S (USA) and Regulation (EU)

The Erostek ET312b

Since the ET312b is sometimes considered not to be compliant with EU electronic device regulations, if shipping it to the EU I highly recommend ordering it from Regulation. I had several friends’ boxes ordered from the USA seized by customs.

Construction

The Erostek ET312b is probably one of the oldest e-stim power boxes which is still on the market. Its design has almost become iconic, the characteristic beige box having been featured on so many porn pics over the last decades – until Erostek changes the design a few years ago to a more stylish black. This design change lead to some discussion in my testee panel. Some – like me – prefer the new look because it fits the style of most playrooms and scene atmospheres. Other likes that the old box popped out and is indeed a classic. If you have an old box and want the new look, there is a kit to exchange the case – or do it the Trikoot way and use alkyd based paint to color the case in your signature color. The case has a rough texture which forgives finger prints while the control panel is still glossy. The box measures 205x157x65mm making is the largest of the e-stim power boxes. This is largely due to the lead acid battery which has a capacity of up to 48h. But which also makes the box with a weight 1.200g making it the heaviest box on the market. When the battery gets old, it can be replaced with a little bit of electro technical know-how but unlike the other boxes which are powered by 9v block batteries, if it runs out mid-scene in a club you can’t replace the battery instantly but have to use the power supply unit. Generally speaking, Erostek sales almost everything as spare parts. So if something gets broken and you are handy, you can fix it yourself.

Detail of the Control Panel

The entire front of the box is taken up by the control panel. The left third is for display information. On top there is a two-line green backlight LCD. Below it there is a hole through which you can adjust the screen’s contrast using a fine screw-driver (which is only necessary in extreme weather conditions) and two red LEDs which flash when channel A and/or B is firing. In the middle there are the main control buttons. The first horizontal pair are the grey buttons Menu and ok. Pressing Menu will get you to the advanced setting (see below) and OK will select the currently displayed menu point. Next to them are white buttons labeled Up and Down. In the menu they are used for navigating. Outside the menu, they are used to scroll through the box’s programs. Next to the Up key there are three rotary controls. The first is “Multi Adjust” to manipulate the current program, the other two are controlling the power level of channel A and B. Below the three knobs there is the power button which starts up the box, the link jack for connecting the ET312b with a computer, 3.5mm jack line-ins for the microphone and another one labeled “Audio”. I have tried the microphone and music on both jacks and got the same effects so I am not sure why there are two. Theoretically the mic should create very faint sensations when plugged into Audio but I did not experience that. Next are the two 3.5mm outputs for channel A and B and last the input for the power supply unit.

Detail of the Display

The ET312b comes with a few accessories: The power supply with adaptors for USA, EU and Canada, two 1.2cm long 3.5mm jack to 4mm banana plug leads, a 2m long line-in cable to connect you phone or MP3 player with the power box, a microphone with a 2.4m long cable and holdfast with a small glue patch to permanently position it somewhere in your playroom (though the holdfast is so flimsy and the glue to weak, I use adhesive tape to position and fix the mic in a suitable position for each scene) and an informative manual. What the ET312b doesn’t come with – unlike most other modern premium e-stim boxes – is a nice carrying case.

Playing with the Erostek ET312b

The ET312b is used like every other box. After pressing the power button a 3 second self-test is run after which the battery’s power level is displayed. After that connect the leads to the electrodes, connect them to the box, select a program and slowly turn the channel’s intensity up until the sub starts to feel someting.  The ET312b has 18 resp. 24 different programs. The last 6 programs are custom once which can be transferred onto the box using the ErosLink software. After selecting a new program there is a short ramping up period. This is to prevent too intense stimulation for the case the power level has not been turned down before the change. This is necessary because every program feels differently intense on the same power output level. The sensation of the programs can be adjusted by turning the Multi Adjust knob.

Program name Sensation Multi Adjust Effect
Waves Wave-like sensation with random wave length and intensity Speed of waves
Stroke Steady wave form on both channels Wave length
Climb Pulsed sensations that increases up to the maximum selected  intensity Climbing speed
Combo Sensation like wave program but changing between the channels Length of stimulation on both channels, simultaneous stimulation when turned all the way up
Intense Unmodulated waves Wave length and feel from soft to spiky
Rhythm Pulses of increasing sensation which’s output will increase each cycle Pulse length
Audio 1 Transforms audio input into same stimulation on both channels Selects input’s sensitivity level: Turn Multi Adjust until LEDs are flashing than start adjusting the channels’ intensity
Audio 2 Transforms left side audio signal into stimulation for channel A and right side for channel B
Audio 3 Transforms left side audio signal into stimulation for channel A and right side for channel B but process the waveform in a unique way
Split Channel A: Stroke, channel B: Waves Speed of waves & wave length
Random 1 Mixes patterns from the first 6 programs for a unique stimulation Alters selection variable
Random 2 Random stimulations at changing intervals No effect
Toggle Constant output on alternating channels Changing speed between the channels
Orgasm Ramping up pulses alternating between the channels Pluse frequency
Torment Brief stimulation bursts with random pattern and random breaks Pluse frequency
Phase 1 Allows for stimulation to be felt in three electrodes on the body Speed of changing between channels
You need special tri-phase cables to experience these channels
Phase 2 Adds changing intensity
Phase 3 Three programs on only two channels

With an output of 80 micro coulombs per pulse the ET312b is the most powerful unit in the market. Through the powerful battery it delivers this output regardless if running on battery or using the external power supply. While most subs do not really need the full power on most boxes, if you are having a real pain pig over, having the extra power in the backhand without having to change the electrodes is good.

Just like the E-Stim Systems 2b, the ET312b supports tri-phasing. This means using a special cable the stimulation can be felt at three areas using only a two channels. Since for this kind of stimulation there is an interaction between all three poles, never use it above the waist!

The Microphone which comes with the ET312b

What sets the ET3212b apart from all other power boxes currently available on the market are the advanced features which you can access through the menu button. These features can be used to customize the power box to your personal preferences like:

  • Turning the ramping after a program change on and off
  • Selecting which two programs should be run in split mode
  • Selecting which program the ET312b should be the default after starting up
  • Choosing a power level
  • Change the feeling of programs

As already mentioned Erostek also sells soft- and hardware to program the ET312b. Through the Eroslink software you can write new programs, alter existing programs also on the fly or choose from 25 new programs to fill the six “hidden” program slots in the menu. I have never used the software myself but tried it at a friend for a short time. While it is powerful, you need a lot of understanding how e-stim works (or trying out a lot on the fly) to really develop new routines. And while the interface is functional, it looks very Windows 95 – which explains why the connection to the box is done via a serial port… Especially if you look for remote control over the internet, take a look at the E-Stim System 2b.

Last but not least: Because the ET312b has been on the market for so long and through the advanced features is considered a “pro box” (even though most people probably will never use the features), sooner or later most e-stim enthusiasts will buy one of these boxes. These makes the ET312b the ideal choice for subs who host traveling tops because it is likely that the top will already know how to use the power box without an introduction.

Conclusion: Most powerful, most sophisticated, most widely used but most complicated power box.

Vyper XL

The E-Stim Systems Vyper XL

Vendor: E-Stim System

Construction

The basis of the Vyper is a rectangular piece of 8mm thick, black, polished plastic which measures 220x145mm. On top of this base plate two pairs of golden sheet electrodes are mounted, each sheet measuring 80x28mm. Using four 55mm long M6 screws a clear 110x110mm and 5mm thick plastic plate can be fixed on top of the base plate and tightened using butterfly nuts. There are two of these plates so the entire base plate can be covered. Depending on the bottom’s dick size, one or two places can be used to torment his dick. At the bottom of the clear plates, the same electrode layout as on the base plate can be found.

There are four terminal pairs on the top and two pairs on the bottom below the upper pair of a compression plate. There is a connection between the upper and lower terminals so even if you don’t attach leads to the lower ones, stimulation will come from the lower electrodes.

Detail of a Terminal a Screw for Tightening the Upper Plate onto the Dick

On top of the board there is a little eyelet through which either rope can be threaded or a carbineer attached. Since the total weight of the toy is 650g, it is a good idea to have something which keeps the Vyper from moving around and thus putting the dick in an unwanted location.

For more compact play luggage E-Stim Systems also offers a short version called “Vyper 2” which is half the size of the Vyper XL reviewed here.

Playing with the Vyper XL

There are two ways of wiring the Vyper: The quick and easy and the more elaborate way. The quick and easy way is always connecting a yellow and a black terminal to one channel of your electro powerbox. This way the simulation direction is left and right and you rule out any chance of short-circuiting your power box. For the more elaborate way, you connect the two alike-colored terminals above each other for a top-bottom-stimulation. In this case you need to place small rubber patches where the top terminals connect to the lower electrodes. Otherwise you will short-circuit your power box! While most premium e-stim boxes can withstand this stress, it is not good for the hardware. Also, you won’t feel almost any stimulation regardless of the power level. Furthermore, make sure that the dick touches the panel you connect the box to. This is especially important with less well-endowed subs.

Detail of how the Upper Terminal connect to the Lower Sheet Electrodes

After the technicalities have been taken care of, now on to the fun stuff. The sensation produced by the Vyper actually depends on the dick size. Since the electrodes have very small mass, the more of the dick covers them, the smoother is the sensation. This leads to interesting mind games: Either endure the dick being pressed more severly for a smother sensation or take less pressure but more stingy e-stim. When compressing the dick, taking it slow and not to extremes is wise. Ironically the cavernous bodies are more sensitive to compression than the balls so do not tighten the top plates to the max. It is actually useful to add a nut or two as a safety barrier. The sensation can be made a bit smoother using conductive lube.

Through the Vyper’s unique layout, it takes a bit of time and experimenting which programs wired which way works best for your sub. For me, programs I never found enjoyable suddenly made sense using the Vyper XL. Playing a little bit with pressure during play – like tightening the lower or loosening the upper plate to “squeeze” an orgasm out of the sub – is also a lot of fun. One sub even managed to cum inside the Vyper just from e-stim.  If you have a “larger” sub, taking single plates off opens a hole new range of play possibilities. Either just fry the glans or polish and sound it while the shaft gets all the stimulation.

Details of a Sheet Electrode Pair

For even more varied CBT scenes, the Vyper can be used without the top plates. Simply use rope or elastic bands to keep the dick pressured against the base plate’s poles while you torment the shaft and glans with (e-stim) pinwheels, pegs, a violet wand or impact play. You can even use wax though it is a pain in the ass to clean off!

Speaking of cleaning, after play spray the exposed areas with a sanitizer and wipe it off afterwards. If you used large amounts of lube, your sub came all over the place or through other means it has gotten completely messy/ dirty, soak it in warm water with dish soap and use a soft sponge. However, take extra care when trying. With so many little gaps and holes, water can linger and cause corrosion!

Conclusion: Unique, little bit bulky design for interesting new, rather stingy e-stim sensations.

E-Stim Systems Black Collection

The E-Stim System Black Collection Bi-Polar Butt Plugs

Vendor: E-Stim Systems

2 ½ years ago E-Stim System introduced their Red Collection, a more “sculptural” approach to their popular (and by me highly praised) bi-polar electrodes. While I liked the shape of the electrodes, the design with red velvet colored isolators and mirror-shine finished poles did not really appeal to the “rough” look I like in my toys and playroom. Also, the sizes were quite “Lady-like”. Naturally I was excited when they turned their Bobble into the Black Collection.

Construction

The basic design are two beads stuck onto each other. They are separated by a black plastic neck which serves as an isolator between the two poles. At the bottom the lower bead tapers into a base which has the same diameter as the beads. Around the base run three (resp. four on the XL) groves for better grip even with lubey fingers. Into the base’s bottom a 4mm hole to plug in 4mm banana plugs is drilled. The plugs are available in four sizes.

S M L XL

Distance to 2nd Neck 83mm 96mm 103mm 113mm
Weight 330g 520g 720g 970g

Detail of the Satin Finish

The upper bead is connected the lower part by a stainless steel screw. At its bottom there is a 4mm hole to connect the upper pole to the power box using 4mm banana plugs. To not short-circuit the e-stim box, the screw-head is isolated with a white plastic separator from the base. Around the banana plug socket these is a little hexagonal socket for easier disassembly when cleaning. This socket is highly useful because the screw is harder than the aluminum the electrode is made out off so it will dig into the material. I have older electrodes which do not have this socket and which have become almost un-screwable.

Like all premium bi-polar electrodes the Black Collection is made out of aircraft grade aluminum which is perfectly finished in E-Stim System’s satin matt finish. Since I have already gotten some reader questions about this topic I want to stress that the toys are indeed silver colored and not like in the promotion pictures black.

Playing with the Black Collection

For basic information on how the bi-polar electrodes perform and how to choose the right size, please check out one the review of other models I have published some time ago. Here I want to talk about how the interesting design produces unique sensations.

The Bi-Polar Plug Disassembled for Cleaning

What sets the Black Collection apart from all other bi-polar anal electrodes I have seen so far is that the split between the two poles is at the top instead of the bottom. So when lying down you can choose either choose between pushing it in all the way to the second neck or let the sphincter wrap around the isolator on the first neck. In this position all stimulation is focused on the sphincter, just like with the Micro. But through the larger mass and surface area the sensation is smoother.  Since the mass center unlike the other electrodes is on the outside the sensation feels… in lack of better words inverted. This is especially interesting when a wave program is used for a fucking sensation. It is still a fucking but with a new, different twist.

When sitting, standing or walking the electrode should be pushed in all the way. Especially when not sitting, the mass center outside the body will make it very likely that the electrode will fall out of the ass otherwise. Pushed in all the way, the sensation moves from the sphincter inside the body. This is a weird feeling, because the stimulation feels like a big, massive surface electrode but isn’t experienced on the skin. Again, it is hard to describe, but it adds a new sensation to the e-stim repertoire.

Detail of the 4mm Socket for the Banana Plug and the Hex Key

Especially the two largest electrodes have enough weight to develop an own movement momentum when the sub’s body moves, for example through walking or making him jump from the stimulation inside him. Depending on the rectum’s physiology the electrode will start to tumble, adding a physical sensation to the fact that electro stimulation flashes up on different areas on the bowel mucosa. Depending on the sub’s anatomy, the upper bead can lay on top of the prostate. So just like when a Classic hits the prostate, only using the upper pole in combination with a pad electrode attached to the perineum above the prostate is an interesting way of tormenting this sensible body part. Some subs can even be trained to get milked that way.

Finally, let’s take a look o how the Black Collection’s plugs perform just as anal toys without added e-stim. While they are fun to ride for more experienced anal players, they are good for training new fistees. Slowly fucking the hole with the two beads will teach the hole to open up and close again, even when the entering object is relatively dull. The beads are also perfectly designed to stimulate the prostate; one testee even developed a technique to how to thrust and twist the plugs just right to prostate-milk his chastity sub.

Conclusion: Uniquely designed high quality bi-polar anal electrode.

Twisted Monk Conductive Bamboo Rope

Twisted Monk Conductive Bamboo Rope

Vendor: Regulation

Construction

A few months ago I talked about Twisted Monk Hemp rope which comes in a number of different thicknesses for different kinds of play. Today’s review item is made out of bamboo fiber which stands out compared to other materials because it has anti-bacterial properties. While this provides some level of protection, if you want to be 100% sure, you have to wash your rope between scenes. Bamboo is softer than hemp, making it ideal for fragile areas like the fingers or the crotch area. Twisted Monk only makes Bamboo rope with 6mm thickness. It can be used for most forms of bondage but is not strong enough for suspension bondage. Like all Twisted Monk ropes the ends are whipped using strong yarn to keep the strands from unraveling. There is about 4cm of rope before the whipping. I prefer to keep it because the slightly unraveled end makes the ends easier to grab but you can cut it off if you prefer a neat and tight end.

Detail of the Whipped End

While Regulation only stocks the “Steel” as a color which is a nice blend of white, dark and lighter blue, Twisted Monk also offers black, crimson, denim, ivory, sunset and violet as colors. As an added feature, a conductive fiber which is not made out of cooper has been weaved into the rope. This allows for electric currency to be transmitted while not triggering metal allergies. This fiber is white and thus even the solid colors like black and crimson have some white spots.

Playing with the Conductive Rope

Switching from hemp or cotton rope to bamboo takes a bit of getting used to. Since it is softer, it hugs the body more, making it ideal for body harnesses (though the thickness of 6mm sometimes lacks a bit of “presence” on the body). But since it is softer, knots also tend to travel a bit. So while the rope is theoretically strong enough for most forms of bondage, I did not really use it as a primary fettering mean but add it to exiting ties.

Charging the Rope with a Violet Wand

The rope opened up a whole new world in e-stim play. Except silver covered cooper wire which is pure sting and agony, the Conductive Bamboo rope is the only large area electrode I am aware of. So suddenly entire legs or arms (always be aware that currency MUST NEVER TRAVEL ACROSS THE HEART!) could be energized surprising my bottoms and through the muscle reflexes even myself. Being soft, it enabled intricate layouts like a helix around the dick (something conductive silicone tubes are too stiff for) or around the toes. The latter is especially fun with a motion triggered e-stim box.

To connect the rope to an e-stim unit pole connection clamps are used. I recommend using isolated ones to keep the connection clamp itself being the connection to the body. Theoretically you can simply push a 2mm pin (4mm banana plugs are too thick) into the rope but the connection is unstable so I would not recommend it.

Connecting the Conductive Rope to an E-Stim Box with A Pole Connection Clamp

Despite the mass and contact area being relatively low, it is enough to counter a conductive loop or pad for example. So to really get the e-stim sensation at the rope position I recommend using a massive butt plug from E-Stim System. Even the smaller Classic or Micro ones did work well so no worries if the sub is anally inexperienced. Alternatively, the rope works also great with a violet wand. This is especially fun when used for a body harness when the currency suddenly flows all over the body.

KinkLab NeonWand Flex Capacitor

The KinkLab NeonWand Flex Capacitor

Vendor: Mister B

Construction

Like all violet wand attachments the rear end is made out of metal to connect the electrode with the want itself. Its round plug measures 23x11mm which is the standard for most modern violet wands. There are some out there which have a different socket size so if you don’t have the NeonWand from KinkLab (which I reviewed here), double check if it is the right size.

Unlike most other violet wand attachments, the conductive part is not made out of glass but conductive silicone. So it is flexible and does not break easily. Over the length of 55mm it tapers and arches a bit back before opening up to the 55mm long head. There the silicone is only 7mm thick so it is very flexible. The head is approx. 30° angular to the shaft which allows for precise targeting during play without the power unit getting into way. After 20mm the head splits into to 35mm long prongs which have slightly curved forward ends. The space between the prongs’ end is 7.5mm.

Detail of the Head with the Gap between the Prongs

Playing with the Flex Capacitor

Before I got the Flex Capacitor I had been playing with Violet Wands for almost half a decade but just with glass electrodes. Through the different material properties of silicone it greatly enriched my play. First, there is the possibility to press a large area of the electrode against the skin. While the small lightning between the electrode and the body has a pinching sensation, pressing the entire head against the skin creates a buzzing sensation – which depending on the power level can certainly be agonizing. Simply running the prong tips over the skin almost feels like a wartenberg wheel being used.

Of course when you lift the electrode off the skin, the lightning occurs again. Like all electricity, it takes the shortest way. When you bring both prongs parallel to the body, both ends emit a lightning. This can be incorporated into play when through slightly twisting the violet wand the lightning jumps from one end to the other. Sadly through the curved ends there is no way to bring the entire head completely parallel to the body to create a “lightning circle”. Yet the small tip size of the individual prongs makes them great for precise targeting.

Detail of the Lightning emited from the Electrode

The gap between the prongs opens up a world of new play possibilities: “Grabbing” body parts with lightning. My testees most often circled around nipples, teased foreskin when still covering the glans or the frenulum when after exposing the glans. While this is good fun the gap could be considerably larger for example to fit an entire dick or just the glans between the prongs. Moving up and down the shaft would probably make for an interesting experience!

Last but not least, there is a practical aspect: Most modern violet wands do not have moving parts anymore which makes them usable for travel. But with the electrodes being made out of glass, even in well-padded cases I was always afraid to take mine on the road. But since silicone does not have this issue, I actually have been taking mine to scenes and play parties quite often since I have gotten the Flex Capacitor.

Conclusion: Innovative violet wand electrode for a new, unique sensation.

Unlike the bi-polar anal electrodes made by E-Stim Systems the two poles are split horizontally, with the ElectraStim Classic Plug they are split vertically. Two polished tapered aluminum halves are connected using acrylic which isolates the two poles. The junction is very well-made with almost no burr so unlike other, cheap electrodes which mimic this style there is not injury risk when inserting the electrode. Around the base two rubber bands are wrapped which provide good grip even with lubey fingers. Theoretically they provide some level of isolation when inserting the plug or taking it out even when currency is running through the plug. However, first I strongly advise against moving the plug while e-stim is one because the alteration of the contact surface can lead to nasty spikes in the felt stimulation. Also when you really grip the base, the fingers will make contact with the aluminum, making it likely currency will flow through your fingers. If you still want to pull or push the plug while it is energized, wear isolating gloves.

To connect the plug with your power box there is a socket for 2mm pin connectors at the bottom of each pole.

While I have gotten the Maxi to review, the construction and handling of the toy are the same for all three sizes. Due to the smaller amount of mass in the sensations when playing can feel a bit different.

Playing with the Classic Plug

The shape of the Classic Plug is the same like most traditional butt plugs which means it gradually opens up the sphincter which makes for easy insertion. To ensure good conductivity I recommend water-based lube. I personally prefer Swiss Navy which has good conductive properties.

Because the two poles are facing each other instead of being above each other Classic Plug offers unique sensations compared to my other bi-polar e-stim plugs. The bad news first: Naturally due to the poles’ position there is no fucking sensation possible. When I started reviewing the plug I went through all the programs on my wide selection of e-stim power boxes. Some of my favorite ones I did not like at all, others I never considered to be fun suddenly became interesting. So when you have gotten only E-Stim System Premium Anal Electrodes, take a look at this one for more varied play options.

Detail of the Isolation Rings Around the Base

Another good news is: All the sensation felt is just centered at the sphincter which leads to an intense stimulation. Even at low intensity settings, strong sensations can be felt. So this plug is good for nuanced play as well as for more tormenting scenes. An e-stim sadist friend of mine grew very fond of the small plug because it gave his sub who maxed all his power boxes a new challenge.

However, what spoils the plug a bit for me is the lack of 2mm pin low profile leads. I searched the internet and could not find any. So sitting on the plug is not possible, lying on it is a bit of a challenge, both will increase the likelihood of lead fracture which limits the bondage layouts I really want to incorporate this electrode in.

Conclusion: Easy to insert bi-polar anal electrode for focus sphincter stimulation

E-Stim Systems Pebble

The E-Stim Systems Pebble Power Box

Vendor: E-Stim Systems

After I reviewed the E-Stim Systems Helix in this year’s E-Stim Special in the spring, I literally got inundated with questions regarding the Pebble. The folks at E-Stim Systems were kind enough to provide me with a review sample so here are my testee panel’s condensed thoughts and experiences with the Pebble.

Construction

The Pebbles design is quite distinct for an e-stim power box: With its convex sides it has an almost hand axe like shape which rests really well in the top’s hand. The back, the top and the bottom are made out of the same high quality, sturdy black polymer all E-Stim Systems’ power boxes are made out of. The convex sides are covered in a rubberized soft-touch material for even better grip. The box is 117mm long, 24mm high and measures 78mm at the widest point. The panel at the front side features two 3.5mm sockets and the power switch in the middle. Behind the power switch the microphone is located.

The upper part of the control panel on top of the box is also symmetrically laid out. On the left and on the right are the rotary controls for controlling the intensity of the two channels. Above them is a blue LED which is on when the channel fires. Between the two intensity controls is the “Adjust” rotary control for manipulating the program’s sensation. Below these controls on the left side are two soft-touch buttons labeled with arrows up and down. They are for the program selection. On the right side next to the buttons are the 9 programs names with a blue LED next to them which flashes in a unique pattern for each program (see below).

The E-Stim Systems Pebble with the Entire Box Content

The box is powered by a standard 9V block battery which’s compartment is on the bottom. So if the battery runs out of power you can replace it easily and quickly during the scene.

Like all E-Stim Systems Premium Products the Pebbles has a lifetime warranty. It comes like all power boxes in a black carrying case lined with foam. If you cut the foam a bit on your own, there is plenty of space for some basic electrodes. Out of the box the Pebble comes with a detailed manual, a battery, 4 pad electrodes and two 3.5mm jack to 2mm pin plug leads. While I can understand the choice so you can out of the box connect the box to the pad electrode it is still a bit annoying because most E-Stim Systems electrodes are laid out for 4mm banana plugs (for more detailed information of the carrying case’s content, read my unboxing).

Playing with the Pebble Power Box

After turning the box on there is a 4se self-test during which the program LEDs flash after each other from the bottom to the top. Then the LEDs go on according the current battery status. If only half the LEDs are on, you should consider replacing the battery. The Pebble will only start firing a channel when a program is selected by pressing the arrow buttons. After the selection it takes between 2 and 4 seconds until the program is activated. Once the program is activated the 9 LEDs flash in a unique pattern. This is a bit annoying because you have to memorize which pattern is associated with which program in order to figure out which is currently active.

Program Name Sensation Adjust Effect Flashing Pattern
Pulse Single pulses simultaneously on both channels Speed of pulses Single LED, moving upwards in the speed of the pulses
Flo Wave-Form Making the wave’s sensation stingier Single LED moving up and down
Split Wave-form on left channel, pulse on right channel Speed of pulses on right channel Two LEDs converging towards the middle, a step after the bottom one blinked
Bounce A pulse alternating between left and right channel Alternation speed One LED converging alternating towards the middle and back
Audio Channels fire corresponding to audio input Microphone sensitivity Outgoing from the middle LED the LEDs light up corresponding to the sound’s intensity like an equalizer display
Milk Pulses which frequency first increases and then decreases again Cycle length Two LEDs converging towards the middle and going back corresponding to the pulses’ speed
Squeeze Pulses which increase in speed until max and start again Cycle length Two LEDs converging towards the middle corresponding to the pulses’ speed
Tease Continuous output which changes from soft to stingy and back Cycle length Two LEDs moving from the middle to both ends and start over
Torment Continuous output which changes from soft to stingy and starts again Cycle length Two LEDs converge towards the middle, pause the and move outward again

Like the Helix the Pebble is an analogue box so the basic feel is very smooth but depending on the program can become quite stingy. Especially for beginners I recommend staying at the smoother side of the possible sensations because the sting of cheap e-stim units drives most rookies away. Still the Pebble packs enough punch for experienced players. The programs range from the basic (Flo and Pulse) to elaborate ones (Tease & Torment) which leave enough room to explore different play scenarios even for more experienced e-stim doms.

Like almost all build-in microphones of e-stim units it is not that great and sensitive. But the Pebble – unlike its big brother – doesn’t have a microphone line-in. So if you want to use the audio feature, place the power switch directly in front of the audio source for a good and detailed input.

Example of the Flashing Patterns indicating the Selected Program

So, compared to the Helix, where does the Pebble stand? My honest opinion is, there actually is no real reason to buy the Helix when the Pebble is available. With 5 more programs and dual output for just £40 more, the Pebble offers a better value for the money in my opinion. However, if you know that you only like stimulation in one place, like to threat your sub with the “Fire” button usage or are looking for more control over the program the Helix is the box for you. But from my experience, having talked with dozens of people venturing into e-stim, most people enjoy the possibilities of dual channel stimulation. So even if you are starting out in e-stim, I would recommend the Pebble and if you want to dive even deeper into this form of play and want the features described above, buy the Helix as your second box.

Conclusion: Basic yet versatile beginner’s power box with good value for money.

SensaVox

The ElectraStim SensaVox E-Stim Power Box

Vendor: ElectraStim

It is becoming a bit of a tradition that after each E-Stim Special I am getting inundated with questions about toys I have not reviewed yet. Despite having already reviewed half a dozen different power boxes there are still popular models out there which I have not covered. This review should answer a few of these questions.

Construction

Like most premium e-stim power boxes the SensaVox comes in a sturdy black carrying case. The inside is lined with foam which has cut outs for the power box, a (spare) battery, the audio adapter and space for cables and accessories. If use the SensaVox just with batteries when playing outside your playroom there is enough space for some pad electrodes, conductive loops, e-stim sounds and even a small bi-polar electrode. But when you open the case for the first time, it is packed with stuff: First there are the essential things like the actual power unit, two 2mm right-angle plug to 2mm pin leads, a 9V battery and an adaptable power supply for all four major socket systems (EU, UK, USA and Japan). The explore the audio features it comes with a line-in cable, a 3.5mm female-to-female adaptor for enhancing the line-in’s cable length, a microphone, a CD-ROM with audio files and manuals in multiple languages. Of cause there is printed a full colour manual in English. For a detailed overview of the box’s content read my unboxing.

The ElectraStim SensaVox with all the Standard Accessories

The SensaVox is one of the larger power boxes measuring 145x81x34mm and weighing 245g equipped with a battery and ready for play. The case is made out of a black polymer with now flex so it has a quality feel. The control panel is charcoal coloured with a bit silver dazzle.

In the top left corner there is the power button. In the left corner you find the Boost button which will increase the output power by 25% as long as it is pressed. Between the two buttons is the modify knob which modifies the selected programs. Below the two buttons at the top there is a red LED segment display and a knob below them on each side. They are to control and display the output level of the two channels. If the channel fires a red LED below the know flashes. Just below the middle of the front there are two arrow buttons flanking a blue LED segment display which are for selecting and indicating the program which the two channels will fire.

The SensaVox with all LED Indicators and Display Turned On

The socket for the power supply is located on the left side of the SenvaVox. On top are the 2mm sockets to plug in the leads for the two channels. On the right side are two 3.5mm sockets. The left one is for the line-in, the right one is the microphone input. The back side is covered with a sticker which not only labels the sockets on the side but also provides an overview which program corresponds with the program number. On the bottom of the back there is the battery compartment.

Playing with it

To get the box ready for action, press the power button, wait 2 seconds for the self-test to finish and then you are good to go. For safety reasons connect the leads first with the electrodes and then plug them into the box. The SensaVox will always boot to the first program. Also, regardless of the position of the knobs controlling the channels’ intensity or the modification they are always (re)set to zero when starting the box or changing the channel. When the channels’ intensity is zero, you can twist the knob counter clock-wise without changing the intensity. I would recommend always turning the know to the 6-o’clock position which with all my other power boxes is associated with the zero position. When starting from this position it takes four complete turns from 0 to the max level of 99. So when starting out at the zero position you have some rough idea in the intensity region you are by just feeling the indicator of the knob. When you turn the knob to quickly the box won’t recognize the input so pace yourself a bit. When you want to punish your sub quickly, press the boost button which will increase the output power on both channel by 25% as long as the button is pressed.

Program Number Program Name Sensation Modify Know Effect
P1 Smooth Continuous output with a prickling sensation Changing of the frequency
P2 Caress A synchronous pulse on both channels which sweeps up and down Adjusting the sweep rate cycle between 0.25 and 20 sec
P3 Swinger An asynchronous pulse on both channels which sweeps up and down Adjusting the sweep rate cycle between 0.25 and 20 sec
P4 Burst Burst of selected intensity and then dropping to zero again. The intensity can only be adjusted during the burst Adjusting the burst rate cycle between 0.25 and 10 sec
P5 Alternate Alternating firing of the channels. The intensity can only be adjusted when the channel is active Adjusting of the alteration rate cycle between 0.25 and 10 sec
P6 Stepper A pulse increasing/ decreasing in three steps. While one channel increases the other decreases. Variation of the pulse frequency
P7 Shooter Channels are shooting alternating pulses Number of pulses per burst can be selected between 1 and 72.
P8 Auto Climb Channel 1: Once intensity is selected, the output drops to zero and starts climbing to the selected level, keeps it for 2 sec, drops to zero and start over.

Channel 2: Continuous output.

Climbing rate per intensity level can be adjusted between 0.05 and 5 sec
P9 Climax The pulse during starts out with a high frequency and low intensity and slows down with higher intensity at the end of the cycle. Cycle rate can be adjusted between 5 sec and 6 ½ min
A1 Channel 1 Modulate Channel 1 fires according to the microphone input Increases sensitivity
A2 Channel 2 Modulate Channel 2 fires according to the microphone input Increases sensitivity
A3 Both Channels Modulte Both Channels fire according to the microphone input Increases sensitivity
L1 Channel 1 Modulate Channel 1 fires according to the line-in input Increases sensitivity
L2 Channel 2 Modulate Channel 2 fires according to the line-in input Increases sensitivity
L3 Both Channels Modulte Both Channels fire according to the line-in input Increases sensitivity

The SensaVox is one of the more powerful power boxes out there. While using the same electrodes with other power boxes I have to set their intensity to between 30% and 40% of the max output before the stimulation becomes noticeable. With the SensaVox this was the case already at between 10% and 15%. I especially enjoyed playing mind games with the boost button. It is a great basis for barter games: Either press it as long as the sub agrees to something or leave him the choice of increasing the intensity or feeling the boost. The max output compares to most elaborate power boxes but the low threshold allows for a fine adjustment and varied play.

Detail of the Sticker with the Program Names

Having been on the market for almost 10 years the programs and modification possibilities are not as sophisticated as on a way larger and more expensive ET312b. It does also not feature fancy stereo audio processing or remote control over the internet as the E-Stim System 2b. Still I love the SensaVox very much. It has no full text display which requires pressing multiple buttons at the same time to induce different levels of modification. It is easy to use and thus easy to explain to new top. The programs are fun and cover all the desired sensations. Neither I nor my testee panel really felt it was missing a stimulation pattern.

One thing which puzzled all testee panel member and me were the different audio sockets for the microphone and the line-in. Cheekily we plugged the microphone into the line-in socket and vice versa – and didn’t recognize a difference. So if you ever spotted a difference between the two sockets, please send me an e-mail.

Conclusion: Powerful and easy to use power box with many way to modify the stimulation.
