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

L3 Both Channels Modulte Both Channels fire according to the line-in input Increases sensitivity

Detail of the Sockets for the Two Channels with the Adaptor to use 3.5mm Leads plugged into Channel 2

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.

Carbon Fiber Pain Stick

Vendor: Mr S

The Mr S Carbon Fiber Pain Stick

Construction

The Carbon Fiber Pain Stick’s basis is a 39cm long carbon rod with a diameter of 2.7mm. Unlike most other carbon fiber rods it is a solid one with a deburred tip. The former minimizes the risk of breaking or splintering, the latter prevents it from causing involuntary cuts. The lower 10.5cm of the rod is covered in isolating rubber with vinyl tips on both sides. Through the bottom tip runs one a nylon string loop.

Detail of the Beburred Tip

Playing with the Carbon Fiber Pain Stick

Carbon is a mean material for an impact toy: Lightweight, stiff, yet flexible. So the blows delivered by it are very stingy making the Pain Stick a delightfully devilish toy which needs to be handled delicately. Just a light tapping on the same spot can cause irritating pain, several blows will leave a welt. Because of that this is a great toy for mindfuck-scenes: The top doesn’t induce much force yet the sensation felt can be intense. The small size makes it an ideal for lightweight toy bags when going out to a bar or for precise targeting. But always keep in mind that this toys isn’t made for warming up the skin so adjust the ramping of the scene accordingly.

Another method of using the Pain Stick is pulling the tip back and flick it. This will induce extremely stingy pain which intensity depends on how far you pull it back and if only the tip or the entire rods hits the sub’s body. When you pull back the rod far enough blows can even be felt through thick leather! On bare skin bruises and welts are likely to occur. Since a lot of force is transmitted this way the target areas should be chosen carefully: On thin skinned body areas like the glans the skin will most likely break, delicate body areas like the balls serious bruises or injuries of the spermatic cord can lead to a visit of the ER.

Detail of the Rubber Covered Grip Section and the Loop

Carbon is a conducting material. So if the bite of the stick itself isn’t agonizing enough, it can be connected to an e-stim power box using a pole connection clamp. Since the e-stim sensation should be felt at the impact point, I recommend using a mass-rich counter pole. When playing on the ass or using the Pain Stick for CBT a metal anal electrode is the best option but a conductive rubber loop around the balls or base of the dick also works. For hitting the nipples a pad electrode attached next to the nipple is the safest option.

Since using this toy extensively on a sub can lead to contamination through sweat, interstitial fluid and blood, proper disinfection is important. Luckily carbon is a very low maintenance material in that regards. Simply wash off the residue with warm soap water, let it dry and spray a sanitizer on it. As robust and flexible carbon is, it sadly can break or splinter. So after ever scene, inspect the rod if it is still perfectly smooth. If not, replace it with a new one. The injuries cause by breaking or splintered carbon fiber are very serious and hard to treat.

Conclusion:  Small delightfully devilish toy with huge pain potential.

Electro Gloves

Vendor: Regulation or Mr S

The Electro Gloves

Construction

The Electro Gloves are made out of a stretchy synthetic material with a conductive fiber woven into it. On top of the wrist is a button for the snap connector making each glove a monopole. The toy comes with a snap-to-2-mm-female connector but this can be easily exchanged for a snap-to-4mm-banana-plug connector depending on which system you are using.

Size wise the glove is somewhere between a size S and M but stretches enough to accommodate even a small XL. The fingers are long so you have to pull them back a bit when you have small hands.

Playing with the Electro Gloves

The Electro Gloves can be used in two different ways: Either with both gloves at the same time or with one glove working as the other pole for a monopolar toy. Regardless if you use one or both gloves they are a delicate toy to play with. Since besides the power output the sensation intensity of this toy is determined by the contact area gently lifting the hand and thus reducing contact area can dramatically increase the sensation. It is a very fun thing to play with but needs practice. It is an especially great mind fuck once the sub becomes aware that lifting the hands (but not losing touch completely!) increases the sensation which will make him afraid of the top’s every movement.

Detail of the Snap Connector, in this picture for 4mm Banana Plug

The sensations these gloves create depend greatly on the skin’s conductivity which is influenced by many factors like sweat for example. I would not recommend using conductive lube to increase conductivity with these gloves. The cloth will take up most of the lube making it useless. Since these gloves require gentle hand wash with a mild detergent and not too hot water getting the lube out of them is more stress than theoretic benefit of better conductivity.

When both gloves are used at the same time they are great for sensation play. More or less lightly touch the sub’s skin and let the gloves run over his body. Especially massages or masturbation are a great sensual experience with these gloves on. However it really takes focus from the active part so that both gloves don’t touch. Otherwise the power box will be short circuited.

How to safely wear the Electro Glove as a Top: Wrap the Latex Glove around the Cuff to prevent any accidental Body Contact

How to best utilize a single glove depends on the other electrode you are using. With a mass rich electrode like a big anal plug the Electro Gloves are great for edging. On the more agonizing side of the sensation spectrum spanking the sub with the glove on adds a shock to the impact sensation. Through the movement you have to take care not to disconnect the gloves from the leads when spanking. A single glove also works really well with skin electrodes like the Whisker or a Pin Wheel. If you follow the electrode closely with just the tip of a finger it might be acceptable to use the electrode above the waist.

In any other case as with every e-stim electrode: Stay below the waist for safety reasons! Especially when you use both gloves together it is imperative that you cover your hand and wrist with a non-conductive glove like disposable latex ones. The Electro Gloves cloth must never touch your skin otherwise there is a chance the currency will flow through your body instead of the subs and thus through your heart.

Conclusion:  Versatile e-stim toy which takes time to master and attention when using.

E-Stim Systems ElectroEgg

The E-Stim Systems ElectroEgg Size Large

Vendor: E-Stim Systems

Construction

The E-Stim Systems ElectroEgg is a bi-polar e-stim toy. Both poles are very short cylinders with domed ends made out of mirror-polished aircraft grade aluminum. They are separated by a polymer divider in the middle which color-codes the size. On one end there is a 130cm long cable with a 3.5mm audio jack at the end. The cable is designed for pull up to 12kg.

The ElectroEgg comes in three sizes.

Size Diameter Length Weight Divider Color
Small 30mm 41mm 70g Magenta
Medium 38mm 60mm 153g Red
Large 50mm 73mm 301g Black

Like all E-Stim Systems premium anal electrodes it comes with a lifetime warranty.

Playing with the ElectroEgg

Getting play ready is easy: Lube up the ElectroEgg all around with water based (conductive) lube and gently push it against the sphincter until it opens up and swallows the electrode. As always when it comes to metal anal toys choose a size which is smaller than the diameter you can take with vinyl or silicone toys because the metal will not give in. Another important piece of advice is that you must not put a condom over the egg. Some tops put condoms over their anal toys when they use it on multiple partners but the latex will prevent conductivity. Being made out of metal and high quality polymer when cleaned properly there is no chance of a STD transmission.

Detail of the Power Cable and the 3.5mm audio jack

The ElectroEgg is the only bi-polar electrode I know off which gets inserted completely into the ass and thus stimulated the colon instead of the anus. The colon is an intriguing spot to apply stimulation because it has a very high density of nerve endings as well as muscles. The sensation the ElectroEgg creates of cause depend on the program of the power box but it’s the only anal electrode I have come across that ever created a dragging sensation or triggered muscles movements and sensations well into the thighs. Especially with the nimble small ElectroEgg combining (deep) fisting with e-stim is a unique sensation that will blow your mind! Since unexpected muscle reflexes can be triggered by e-stim the top should be prepared for the fisting to be a bit different than he is used to.

Speaking of size and weight: The ElectroEgg is also fun without e-stim in everyday situations. Putting it inside the colon and going for a walk or working out will cause the more or less heavy metal object to move inside the colon which triggers the never endings or stimulates the prostate. One of the testing tops made his sub perform jumping jacks… Of cause if you combine the electrode with a remote controlled power box this even adds to the fun…

The ElectroEgg Disassamble for Cleaning

When the top is careful with the cable and wears an isolating glove the ElectroEgg can also be used as a skin electrode by being rolled over the skin. The effect is like using a bi-polar pinwheel but through the larger mass and contact area the sensations are way smoother.

As written above E-Stim Systems says that the cable can withstand pull up to 12kg. However I would not recommend to pull it out of the ass alone but just use light pulling as support when pressing it out. A sphincter can hold onto things with way greater power than 12kg so there is a chance you can damage the cable if you just pull.

Once outside you can screw both halves apart was them in hot soapy water, let them dry properly and finally spray your preferred sanitizer on it before screwing them together again.

Conclusion: One of a kind bi-polar electrode which creates unknown stimulation.

Kinklab NeonWand

Vendor: Regulation

The Kinklab NeonWand

Construction

Like almost all violet wands the NeonWand consist of two pieces: A power unit which has a socket on top for interchangeable electrodes. The power unit of this model is 23.5cm long and has an average diameter of approx. 45mm. Inside is a solid state power unit which means there are not moving parts like in traditional power unit. So moving the toy won’t affect the sensation delivery. The lower ¾ of the power unit is covered by a soft textured material for better grip. On top is a 12.5mm socket for the electrodes which is the diameter most violet wands use today so most electrodes from other manufacturers should fit. At the bottom of the power unit is a rotary control for the intensity and the 2.3m long power cord.

The NeonWand comes with four electrodes made out of glass and filled with a noble gas:  A comb shaped one and three rods with a mushroom head, a small probe head and a tongue head.

There are two versions of this toy: A white power unit with purple glowing electrodes or a red and black power unit where the electrodes glow red. The toy comes in a cardboard box outfitted with foam to store the electrodes safely. There is also a detailed handbook on how to use a violet wand.

The Electric Arc and Purple Glowing Argon inside the Electrode

Playing with the NeonWand

Violet wands work much differently than the TENS units I have reviewed so fare. The power unit is a Tesla coil which produces static electricity. The currency doesn’t flow through the body but an “electric arc” appears when the electrode comes close to the body. If the electrode touches the skin just warmth is felt. Since no currency is flowing through the body the violet wand can be used on almost all body areas (but the eyes which is an absolutely forbidden area!) safely. It is advisable not to use a violet wand for an extensive period of time at the same body area. Burns like sunburns can occur. I would actually recommend using a moisturizing lotion after using a violet wand to clam the skin.

Unlike TENS e-stim units violet wands don’t have stimulation patterns (more commonly called “programs”). Only the intensity can be adjusted. Depending on the electrode the sensation can range from a light tingling to excruciating pain. The NeonWand is not the most powerful wand out there but it is certainly powerful enough for an interesting scene.

As with all e-stim toys conductivity is the key to the sensation which is influence by three factors when it comes to violet wands. First there is the electrode’s conductivity. Most violet wand electrodes are made out of glass and filled with a noble gas; these are quite conductive. There are metal and conductive silicone electrodes out there which have better conductivity and thus stronger sensations. Second there is the skin conductivity which is influenced by many factors like sweat for example. Improving skin conductivity can be achieved by conductive gels, water-based lube or heavily moisturizing lotions with urea or zinc oxide for example. This can be used to creating a “ladder” out of conductive strips so the intensity keeps changing while you run the electrode over it.

The Four Electrodes which come with the NeonWand: The Comb, the Mushroom, the Probe and the Tongue

Third there is the contact area. This is where the different electrodes come into play. While the Probe and the Mushroom are just different contact area sizes which don’t change you can use the comb and the tongue creatively. Just twist and turn them to alter the contact area. All electrodes can be used to inflict sensations on conductive materials like a chain wrapped around the subs. The longer and thicker the chain the less sensation is felt so I recommend using only thin otherwise the power unit will not be powerful enough to induce a noticeable sensation. Generally speaking a violet wand is best used to sensation play or teasing e-stim sessions. Since you can move around the electrode quite freely sensations can be spontaneously induced on surprising spots of the body.

What is important to keep in mind is the material of the provided electrodes. As much fun/ agony are they are on “moist” body areas as the glans of an uncut guy or the anus I strongly recommend against inserting them into the body. The chance of them breaking is simply too high.

Conclusion: E-Stim toy for tickling and torturing with a dramatic visual effect.

ElectraStim Bi-Polar Soft Genital Clamp

Vendor: ElectraStim

The ElectaStrim Bipolar Soft Grip Clamp

Every time when the E-Stim Special is on one of the most things I get asked about is e-stim on the nipple. But since almost all clamps offered are monopolar I strongly discouraged using them above the waist in order not to interfere with the heart. I got so annoyed with the lack of adequate bipolar clamps that I build some myself with copper electrodes which wasn’t ideal either. So I was very excited when I discovered this clamp by ElectraStim which they sent me to test thoroughly.

Construction

As the name of the toy suggests the general design follows the one of a rather large clamp with an overall length of 103mm.

Detail of the 2mm Socket

The bottom half of the clamp are two handles made out of a black polymer connected by a hinge. Below the hinge is the spring which pushes the tips together. The bottom of each handle is a large, slightly domed area for better grip at which bottom the socket for 2mm plugs is located. The top half is made out of flexible yet sturdy wire. The tips are round and slightly domed with a diameter of 12mm. With standard ElectraStim leads attached the maximum aperture of the clamp is 38mm.

Playing with the Bi-Polar Clamp

Despite the little amount of mass and the small contact area the clamps can produce a quite smooth sensation making it a suitable toy for beginners who are not into sharp and stingy pain.

Detail of the Electrode’s Contact Area

As written above this clamp is bipolar so the currency flows between the two tips of each half making it safe to use on the nipples. But through the wide aperture this clamp is quite versatile. Besides the obvious nipples I used the clamps to fry balls or place if in the glans with one electrode on the frenulum to milk and e-stim orgasm out of the subs. The most fun I had was attaching the clamp to body parts otherwise not exposed to e-stim because the sensation is most surprising to the sub. Tormenting the nasal septum with excruciating pain will bring most subs to their knees and ultimately to tears. On the other side of the sensation spectrum a light tingling program on the ear lobes is a great addition to elaborate sensation play.

Maximal Aperture of the Clamp

The stiffness of the spring is relatively low and the tip is smooth and round which makes this clamp comfortable to wear over long periods of time. The downside of this is that if you can to attach the clamp to small body parts like the male nipple, it will slip off very easily, especially when the sub moves around through the induced sensation. I got around this problem by attaching the clamps perpendicularly to the body and put a cloth pin on top of the ElectraStim clamp. It is important to use a cloth pin which is not made out of metal otherwise you will short circuit your power box!  Alternatively wrap an elastic band several times just below the tip of the clamp.

Two Options to Increase the Spring’s Stiffness

It is imperative that when you use a clamp on each nipple that the power box has two completely isolated channels and use one channel per clamp. Otherwise the might be interaction between the two clamps which can lead to currency flowing between the nipples which than ultimately can cause heart problems.

Conclusion: Versatile and safe to use e-stim clamp.

E-Stim Systems Helix

Vendor: E-Stim Systems

The E-Stim System Helix

I often get asked “Which is a good and safe e-stim box to start with?” For years E-Stim Systems Series 1 was the most inexpensive of the premium boxes. In March this year they launched the Helix as a replacement. I was very glad when they sent me a review sample for the E-Stim Special to finally be able to bring you a review on the lower end of the price range.

Construction

The Helix measures measures 111x67x28mm and thus is still one of the more compact boxes available. The case is made out of a high quality, sturdy black polymer. On the front of the box is the power switch and the output socket for 3.5mm jack.

The top of the box is the control panel. On left there is a small blue LED which fleshes when the box fires. Below are three rotary controls for the intensity level of the stimulation, one to alter the feel and one to alter the speed of the stimulation. Below the controls there are five LEDs which indicate the selected program. Below them there are two buttons: The one on the left is called “Fire”. When you press it in Fire mode an intensity burst is fired. When holding the button down while turning the box on the output level increases significantly. The right button is for shuffling through the programs.

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.

Detail of the Power Button, the Output Socket and the Three Controls

The Helix comes in a high quality and nifty nice black carrying case along with a detailed manual, a lead, four pad electrodes and a battery (For detailed pictures take a look at my unboxing). As all the E-Stim Systems Premium Products the Helix comes with a lifetime warranty.

Playing with the Helix Power Box

To get the Helix play ready push the power button and wait for the short self test which also checks the battery. If less than half the LEDs flash you should replace the battery. Connect the lead to an electrode and the box and attach the electrodes to the sub. Then select your desired mode. The Helix will always start up to the pulse mode. Finally slowly start turning the level control clockwise until the sub starts to feel something. Being an analogue box you can very finely control the box with the rotary controls.

Program Name Sensation Feel Alteration Speed Alteration
Pulse Sensation pulses Makes the pulses’ sensation sharper Frequency of the pulses
Flo Continuous output Makes the sensation sharper No effect
Fire Continuous output when the fire button is pressed Makes the sensation sharper No effect
Milk Pulse waves with increasing and decreasing speed Makes the sensation sharper Wave length control
Tease Random sensation Range and amount of pattern change

Since the Helix is an analogue box the sensation is silky smooth – if you don’t adjust the level and feel to be otherwise. This makes this box good for beginners because the sharp and almost excruciating sensation of cheaper box drive many people away from e-stim. The five programs cover the basic range of possible e-stim sensations from a light and arousing tingling over milking to extremely challenging pain. And despite the relatively price point the Helix produces enough output to be interesting to experience players, especially in the high intensity mode.

Detail of the Battery Compartment

It is only in the features you realize that it is a beginner’s box: It only has one output channel and not extra inputs like a microphone or motion sensor. But if you just want to get a first glimpse into e-stim or need an additional box with a fire button to control your sub, this box offers great value for an attractive price.

While the pad electrodes of the basic set are good for first dip into e-stim, I recommend investing the £10 more for the Helix Blue which comes with a set of conductive rubber loops (which I consider an e-stim essential as you can read here).

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

E-Stim Systems Stuffer

Vendor: E-Stim Systems

The E-Stim Systems Stuffer Bipolar Anal Electrode

The E-Stim Systems Premium Bi-Polar Anal Electrodes have been getting rave reviews from me since I started reviewing them. So when they asked if I wanted to take a look at their new surface treatment I was al for it – and discovered another major improvement.

Construction

With the basic from like a butt plug the Stuffer is shaped like any other toy from the E-Stim Systems Torpedo Range. The head has a diameter of 6.25mm and a length of 9cm. It takes 3cm from the tip to reach the maximum diameter so this plug is rather dull. The neck has a diameter of 38mm and is 22mm. Both the head and base which is 40mm long taper towards the neck for a more comfortable fit. For easier grip while playing the base features four grooves. With an overall length of 152mm you get a lot of metal which results into a total weight if 955g.

The material and production quality it top notch! The screw connecting the top and the bottom is stainless steel and the plastic is quite sturdy. The piece de resistance is the aircraft grade aluminum the head and the base is made out of. In March E-Stim Systems introduced a new surface treatment which give their anal electrodes a more even, satin like matt finish which liooks great.

Left: An E-Stim Systems Large Torpedo with the Previous Finish
Right: E-Stim Systems Stuffer with the New Finish

E-Stim Systems so convinced by their build quality that they give a lifelong warranty and having been using these kind of electrodes extensively for almost 5  years I have to agree. Even the plastic hasn’t aged. Yet there is a drop of bitterness with the combination of the aluminum head and the stainless steel screw: Since the screw is harder than the material the thread is cut into, if you tighten the screw too tight too often the thread will get a bit dull. With my old electrodes this made unscrewing both parts a bit difficult. But E-Stim Systems fitted the Stuffer with a hexagon socket at the bottom of the screw so you can now use a hex key for easier unscrewing.

Speaking of screw and thread, for easy cleaning this toy is made out of five individual pieces: Through the base a hole is drilled. Into this hole a plastic insulator is put into which the screw is put. Onto this screw you put another piece of plastic which forms the neck. On top of this you screw the head of the electrode. Into the base and the connecting threat holes for 4mm banana plugs are drilled. The holes are far enough apart for using low profile plugs so you can comfortably sit on this plug.

Another neat thing is that the toy comes in a nifty and stylish black box that can be adjusted length-wise. So if you don’t store your e-stim toys in them but display them proudly you can store other stuff like clamps in there. I use one of the larger boxes for band-aids and the a thinner one for sounds.

Playing with the Stuffer

Since nothing has changed in the way the Premium Bi-Polar Electrode performs this section is a copy and paste from older reviews of this toy.

First a piece of advice on how to read this section: I will only discuss how the physical properties influence the sensation. The sensation itself depends very much on your e-stim box and the program you select.

Detail of the Hexagonal Socket for Easier Disassembly

When choosing the right electrode before play there are three important things to keep in mind:

  • The Material: Unlike other soft materials like vinyl or silicone most anal toys are made out off aluminum will not yield! So if you can barely fit a 64mm vinyl plug into your ass taking the Stuffer will at least take some training, especially because the dull top makes it hard for the ass to open up. If you sphincter isn’t exceptionally well trained (I am talking taking a fist without much pre-stretching) I highly recommend pre-stretching with softer toys which have steeper slopes. But you will get rewarded with a REALLY stuffed feeling. Especially when walking around that if you walk around and your hole gets loose there is a chance of almost 1kg of metal hitting the floor which isn’t good news for tiles or hardwood floores…
  • The Handling: A lot of people put condoms over their anal toys when switching partners. The condom’s latex layer will at best alter the way the current flows thus might produce unwanted effects, at worst no current will flow at all. But because the metal is easily cleaned and disinfected this isn’t a big issue if you clean your toy thoroughly after using it on one partner. The best way of cleaning this toy is to disassemble it, put it into hot water with a bit of detergent added to it. Scrub with a soft brush, rinse the water off and let the parts dry. Once they are, spray your preferred sanitizer on them and assemble them again once dried.
  • The Lubrication: When it comes to lube I would always recommend water-based lube. The glycerin in the lube will help the current flow from the metal to the skin. A thick layer of silicone lube can produced unwanted effects.
  • There are specialized electro lubes out there but in my opinion they are overrated. For my sessions I use Swiss Navy water based lube. It keeps it gliding properties for a long period of time and transmits current very well.

The E-Stim Systems Stuffer Disassembled for Easy Cleaning

When it comes to e-stim a good rule of thumb when it comes to the sensation is !the larger the mass and contact area of the electrode the smoother the sensation”. Since this is the heaviest and larges anal bi-pole I own the sensation was as expected silky smooth. But unlike the other electrodes the mass difference between the base and the head is so large that the sensation is nearly only felt at the base. It was a weird, hard to describe feeling putting the stroke program on. Usually this created a fucking sensation. This time… it was not bad just different than expected.

Of cause you can also use the electrode also as a monopole. Just plug one banana plug into the anal electrode and the other one onto another electrode, a pin wheel or a rubber loop for example.

Conclusion: High quality bi-polar anal electrode for real ass pigs.

Flick Duo Power Box

Vendor: ElectraStim

The ElectraStim Flick Duo

Construction

The Flick Duo is one of the smallest e-stim power boxes out there. It measures 96x57x16mm. The case is made out of a high quality polymer. The bottom is black with a satinlike feeling while the control panel has a grainy texture and is surrounded by a little bit raised silver frame. The top half of the control panel is symmetrically laid out: There are raised buttons soft buttons with a nice pressure point labeled plus and minus to control the intensity of the two channels. The current selected intensity can be seen on a digital display above the controls. Below the controls are orange LEDs which are on when the channel is firing. Between the two channel controls are four green and one red LED which display the intensity of the kinetic recognized by the power box.  Below this scale there is a digital display which indicates which program is currently selected. The lower half of the control panel has two buttons. The upper one is for cycling through the programs. When the green LED left to it is on you are cycling through the 8 regular programs. When you hold the program selection button for approx. 5 seconds the right LEDs goes on which means you can now cycle through the 4 flick programs. When changing modes please keep in mind that holding down the button will cycle one program further in normal mode until the mode change takes place. The lowest button is the power bottom. Next to it is a red LED which comes on when the battery level is low.

Detail of the Two 2mm Sockets

There are only three sockets on this power box: Two 2mm output sockets for the two channels and a Mini-USB socket at the bottom. If you want to use 3.5mm plug leads ElectraStim offers adaptors for 12€.

The small form factor is partly due to the build in battery which lasts between 4 and 6 hour of play depending on the intensity. This feature was heavily discussed among my testees. Personally I prefer power boxes which uses 9V block batteries (also known as PP3). I usually carry around a bunch of them at an even so when one gets empty I can replace them easily or take a battery out of another box. For the Flick Duo I theoretically have to carry a power bank. But the small form factor was really appreciated by some testees (especially the ones who are not like me and travel with a ton of electrodes) saying it is a very discreet power box which can easily be stored away during public play for example. Once the Flick Duo ran out of power you can use the provided Mini-USB cable to charge it which takes approx. 3h.

The Flick Duo comes in a nice black box along with a detailed manual, two leads, four pad electrodes, a Mini USB charging cable and a drawsting storage bag (For detailed pictures take a look at my unboxing).

Playing with the Flick Duo Power Box

In order to get the box ready to play simply push the power bottom. The box will go through a little self test and then you are ready to play. The box will always start in the first program and with both channels turned down.

Program Number Program Name Sensation
1 Continuous Permanent stimulation from both channels
2 Alternating waves Perpendicularly raising and falling sensation on both channels
3 Escalating Simultaneous Wave Raising and falling sensation on both channels with first increasing and than decreasing speed
4 Alternating Pulse A short burst alternating between the channels
5 Escalating Simultaneous Pulse A pulse on both channels which increases in speed
6 Simultaneous Falling Rest A pulse on both channels with the time between two pulses getting shorter until the stimulation is permanent
7 Alternating Dual Pulses Pulses first slowly alternating between the two channels, than quickly before starting over
8 Rapid Fire Escalation Alternating between both channels the number of pulses increases by one each time until 19 pluses are reached and then starting over again

After pressing the program selection button for 5 seconds you switch into Flick mode which offers you four programs.

Program Number Effect
1 Left output is Flick sensible, the right is permanently on
2 Right output is Flick sensible, the left is permanently on
3 Both channels are flick sensitive
4 One channel is only active. After a certain amount of sensation has been induced on one channel, the other becomes active.

The ElectraStim Flick Duo turned on in normal mode

In Flick mode the box will fire when exposed to up-and-down motion. I would describe the sensitivity as medium. I attached the Flick Duo to my wrist when jerking off and REALLY had to beat the meat in order to feel something. Generally speaking you really have to concentrate in which way to move the box in which intensity to get the desired effect which at least in my case took way too much mental effort to jerk off properly. So instead of a self pleasure enhancer the Flick Duo is a sophisticated pain play tool. Attaching it to the top’s wrist (and the leads along the body which enough slack for him to move around!) when flogging or spanking adds a new dimension and range of sensation to impact play. The Flick mode can also be used a bit like the audio input on other boxes: But instead of putting the mic in front of the sub’s mouth so he has to control himself in order to make the stimulation stop with the Flick Duo the sub has to be tied standing up with the above his head and some degree of being able to move his feet to “work” sensations out. Now hang the Flick Duo from his balls and attach electrodes either to his junk or if you are really evil use pad electrodes on the soles’ of his feet. Kick the dangling box to get it started and watch him jump around trying to cope with the stimulation which inevitably creates more stimulation.

Conclusion: Small e-stim power box with movement triggered stimulation feature.

Oxballs Nutter Electro Sacksling

Vendor: Uberkinky

Construction

The Oxballs Nutter Electro Sacksling

The Oxballs Nutter Electro Sacksling is a sheath for putting around your balls. It is made out of their super-stretchy and easy to care for FLEX-TPR. The Nutter comes in black, smoke clear, clear and clear read; the e-stim version is only available in clear. The top is designed like their very comfortable, long-time wear proven Unit X sack slings. The bottom features a sack for each ball. While the TPR around the balls is thinner there are reinforcement veins which help compress the sack to fit even smaller balls. At the bottom of the sack there are two holes either to drain swear or for the electrodes’ socket. The electrodes are two aluminum disks with a diameter of 22mm and each weight 9 grams. On the bottom of each disk there is a 25mm long tube with a hole in the middle which serves as a socket for 4mm banana plugs.

Detail of the two Aluminum Electrodes

Playing with the Nutter Electro Sacksling

As with all tight Oxballs nutt toys putting this one on is a bit of a challenge. I highly recommend shaving the crotch area well because getting hair caught by the TPR can REALLY hurt. Before putting the Nutter around your balls I recommend putting another Oxballs cockring around your balls to keep them from retracting into your body. Than stretch the opening hole wide and stuff your balls into the sheath; this works best with a third hand if available. Some testees managed to get their balls into it by turning the sack inside out, placing it onto the balls and flipping it back.

While the FLEX-TPR is resistant towards all forms of lube I do not recommend putting lube into it trying to make putting the Nutter on easier. The lube will get everywhere and you won’t get any grip anymore.

Detail of the Unit X Neck Design

But this bit of stress is way worth it. First there is the fetish aspect. With the Nutter on your balls look and feel bulkier and heavier, almost as if they have been pumped. There are also new sensations: The larger the scrotum, the more constant pressure is applied to the balls. It is not much but a constant, subtle and for mist CBT aficionados horny stimulation. The neck of the Nutter adds a little stretch which creats a unique sensation when cumming: The stretch keeps the balls from coming closer to the body which makes climaxing a bit harder yet more intense when finally getting there while the pressure tries to squeeze the cum out of your balls.

Detail of the Supporting Veins and the two Electrodes

If you get the e-stim version the fun gets even more intense. Since it comes with two electrodes the Nutter can be used as a bipolar toy with the sensation focusing on frying the balls. Especially with a remote controlled or motion triggered power box you can quite authentically recreate the feeling of getting kicked in the nuts. As a monopole – either with just one electrodes or with both daisy chained – using a monopole cock toy is the most fun because the currency travels along the many nerve endings along the shaft. For this kind of play an e-stim sound is the best counter electrode.

When you want to use the Nutter for e-stim you have to place the electrodes before putting the sheath on. Despite the TPR’s snug fit around the sockets they become a bit loose when stretching it to put the sheath on. Because of that I recommend attaching the leads before putting the Nutter on so you have something to hold onto.

Maintenance is quite easy: Simply wash it with warm dish soap water and let it dry. Afterwards spray a sanitizer on it. I recommend storing it not touching any other toys otherwise they might disintegrate each other.
