From the ET312 to the 2B to the Sensavox to the Axis. All the technologies, all the features, all the things that can make you scream out in joyful ecstasy, now in a unit that fits in the palm of your hand, with no need to connect it to a power socket, and still delivers enough juice to get your juice flowing. It's incredible how far things have come. I only wish that the box uses a more standard 3.5mm output for easier connection to other brands' electrodes. Other than that, this is the best use of my annual bonus so far.

Have only started getting into the different features. A big step up from my Flick Duo, haven't gone anywhere near the higher power levels.
Looking forward to trying everything out.

This is one of the best products I have bought, it may not be the biggest dildo but it makes up for it with the added sensations you get from the electrodes on the sides. Whether you use it as a strapon or hand-held it takes your breath away when it is pulled out while on. I would recommend this to anyone into e-stim.

Just what I needed

Not going into detail, but purchase has definatley not disappointed.

Fulfilled the desired effect

If you like to stim and you like to edge then this is the device for you. Slightly expensive but for example using the proximity mode you can get to the edge and get very precise increases or reductions in sensation to keep you where you need to be.

Great Service

I only purchased this device very recently, so it's early days yet, but I think I now know enough to write this review. I notice that on the unit itself, it is described as a novelty item. Overall, I'm not unhappy with it, but already some of the novelty is beginning to wear off. I've tried more than once the feature which uses a microphone to influence the output of the device. Basically, I couldn't get that feature to work. Even with the sound source set at full volume and the controls of the unit cranked up to max, I could barely detect any impulses at all. I got a similar result when I used the supplied audio input cable. Perhaps I was trying to use the microphone or audio inputs with the wrong accessory. I'll try it again with other accessories when I get them. The other programs and features, which don't require a microphone audio input, all seem to work more or less as described. I do like the fact that it's designed with safety in mind. I think that's important because surely no one wants a nasty unexpected shock because they pressed the wrong button.

I got the medium and large version as I fancied a challenge. The medium is just about perfect size for me, the large takes a little bit of persuading, but pops in nicely. They’re great fun to use without the electro side, but with it turn on… Oh my goodness!! Highly recommend.

Ok, let's be clear: I do like big things up my bum. One of my favourite toys is a combined cock ring and anal insertible with a diameter of 5 cm that I wear regularly and for prolonged periods.

Yet, the medium invader is ... big! Happy I did not go bigger: it was borderline, I struggled to get it in the first time, my heart racing. But once in, OMG, beyond satisfying! And that was before starting the e-stim! The latter created a feeling unlike anything I've ever felt before. Have not even begun to explore all possibilities yet! Very happy with purchase. And happy did not go bigger: the medium clearly pushed my limits more than enough!

Really big improvement on the EM80 I bought some 6 years ago ( which is still working just fine) For me the range of settings and greater power just set the flux above by a fair bit. It comes in a nice case with enough to get started but I would advise trying all the toys as they enhance play considerably.

Bought one of these a while back.
Using it on my cock, my wife can dial it right up to 25 and it's a bit of yawn.
On my balls at max power is a mild challenge, but I can comfortably pleasure her still.
With a prostate probe is more of a hit.

To be honest, I've got a Med-Fit 1 and a Med-Fit 3 dual channel TENS machines which sell for about £26 and are much more powerful than this. I can't get past level 7 out of 10 on any area without cumming. 4/10 on my balls is as far as I can handle without buckling in half and feeling like my nuts are being full on punched.

They also take 9v rectangular batteries which is far better than having to recharge.

Sorry Electrastim, but that's an honest review.

I've used all the sizes, from 5mm to 9mm. Each has their merits. I've found they work best with the metal scrotal loop, although I've not tried an anal probe, which may be better. The 5mm goes in real easy, and has an intense stimulation , especially when it's slowly drawn towards the penis tip. The 9mm is awesome when first used. It really fills the urethra and is indescribable. It has to be drawn up slowly, and the sensation is deeper. The 7mm is somewhere between the two. They can bring you close to orgasm but I've not kept one in during that. Well worth trying.

Am very impressed with the array of programmes experienced so far and the scope for creativity included in the unit, so is my partner btw and once I plug it into my music studio the rhythms will roll, well pulse lol.
Well built, excellent packaging, looking forward to many shocking but happy hours of fun using it.
