Sorry, boys: He won't get bigger, longer or thicker with e-stim, and six pack abs are not going to happen, either.

The principle behind e-stim is that it stimulates the nerve ends, not muscles or tissue. Of course, the stimulation current will flow through the muscles that touch the conductive areas as well, but muscle tissue requires lower frequency and higher impulse rates for training, both of which our devices reach only at the very egdes of their settings. The devices are aimed at the nerves - with higher frequencies and lower impulse rates. To train with these is a bit like eating soup with a fork: You'll get there eventually, but it's not really practical.

But: Our e-stim devices are medically recognized and can be used in a medical context, meaning that they are capable of strengthening the pelvic floor and the constrictor and can be used for pain therapy.

If your loop is made of uncoated metal, we recommend you don't, because the metal may warm up when there is current flowing through it. To be on the safe side, please ask you gynecologist about the material.

Not necessarily. Metal does conduct current better than tissue and if the current comes near the piercing, it may jump to it and make it warm up. If this is uncomfortable, we recommend to take out the piercing.

Not necessarily. It is very important to talk about it to a doctor you trust. If you don't want to reveal the erotic component just ask if you can safely use a stimulation current device to help with back pains - this works with the same principles and everywhere your doctor gives you a go for that, you can go ahead with the toys. It is, however, much better to talk about it openly and make quite sure you know what is safe so that your pleasure won't interfere with your health. As always: Safety first.

Finding the right size is crucial in order to guarantee the best results of your cock ring: If the ring is too big, it doesn’t do the trick, or might even fall off. On the other hand side if you chose a ring which is too small, it might lead to medical problems. Therefore please always ensure that your cockring fits tightly, but is neither unpleasant nor painful at any time.

You can measure the right size by wrapping a piece of non-elastic band around your testicles and penis, so that the ends of the band meet on top of your penis, close to your body. Pull the band tight, so that it feels still comfortable. Mark the band on both sides, where the ends meet and measure the length in mm. Now divide this length by pi (3.14) in order to find out your diameter.

Diameter of the cock ring = length in mm / π

We recommend repeating this measurement on some days and various day times because there might occur natural fluctuations.

Again: When in doubt always choose the bigger diameter.

Never put on the cock ring on an erect penis. Start by carefully tucking in one testicle at a time and then insert the penis into the ring. Never wear the cock ring for more than 30 minutes and always remove the ring gently if needed using a lubricant (like our Bonnie & Glide).

Ah, yes, the Wikipedia entry. That one is written with quite a bit of prejudice and paints a far more excentric picture of electrical stimulation than necessary. Before we go through the various claims one by one, let's look at some facts: There is an enormous difference between alternating current and continuous current, and of course between low voltage (below 500V*) and high voltage (more than 500V*)

Our devices work with continuous current in low voltage.

The difference between continuous and alternating current
Alternating current (AC) - what comes out of the wall outlets - is a lot more dangerous than continuous current (CC). For every AC hertz that flows through your body, your body will register two impulses - the negative and the positive one. This happens because in each AC impulse, the polarity changes once from positive to negative, while in continuous current it stays the same. So at 50 Hz - that is to say, 50 impulses per second - the body feels 100 impulses for AC, but only 50 impulses for CC. That is the medical definition of high and low voltage. In electrical engineering, the threshold is set at 1000 V.

Why is that important? Becaus ethe body itself communicates via electrical implulses that are sent along the nerve tracts to and from the brain, organs and sensors (skin, nose, eyes, ears).

If a nerve tract gets two impulses of different strength at the same time it will carry only the stronger one. So if the e-stim device gives off the stronger impulse, the body's own will be overwritten.

This opens a range of quite exciting possibilities for our purposes because e-stim is applied only at the nerve ends where impulses can only be received, not produced or interpreted.


Where it gets dangerous
The only way to cause problems is to send the stimulation current through an area that produces or interprets the body's own frequencies - the brain where all impulses are interpreted and new ones are produced, and the heart that created its own impulses completely independent of the brain. If you overwrite these frequencies it can get dangerous - and with alternating current twice as much as with continous current.


The greatest danger with sending current through the heart is ventricular fibrillation. The so-called fibrillation threshhold - the intensity of electrical current that can lead to ventricular fibrillation in a healthy adult - is at around 200 mA for continuous current. Our devices can't do more than 80 mA - less than half the dangerous amount. So: No heart failure from us.

If you brave an internet search for the dangers of electrical current for your body, please keep in mind that for the most part, the information you get doesn't differentiate between AC and CC at all, and that the studies you will find nearly always assume a current that accidentally flows through the heart. And that is the one thing we can't say often enough: Don't send the current through your heart.

The thing about the electrical shock
A garden variety taser runs with
a voltage of up to 10.000 Volt
and an intensity of up to 14 Ampere.
An electrical fence for cattle or sheep or something also has
a voltage of up to 10.000 Volt
but only an intensity of around 0,01 Ampere (10mA).
Our devices produce
a voltage of 40 Volt
and a maximum intensity of 0,08 Ampere (80 mA).
Instead of a long read, we'll give you some data to compare for yourself:

The voltage of continuous current is rated as dangerous

from 120 Volt for adults
from 60 Volt for children.

So you can see: Our 40 Volt are definitely no suitable candidates for delivering electroshocks.


How to get burns and tissue damage
It is true that, if much current flows through little space, there can be burns. That's why we always remind you to first place the toys and then crank up the intensity. Burns depend on how much skin touches the poles and how strong the intensity or the current is. This relation is called the current's density, and it varies inversely with the amount of contact area. So if you double the contact area, the current's density is cut in half. A density of 10 mA / mm² can lead to redness, and from 20 mA / mm² upwards, marks or blisters are possible.

In short: With your e-stim device set to the maximum of 80 mA, both poles must touch more than 8 mm² of skin. That keeps the density under 10 mA/mm² and nothing happens (that you don't want to happen). So as long as you stick to the golden rule first place it, then turn it on, you're good to go.
