It took us a long time to write this review because it took us a long time to get up the nerve to use this thing more than once. Once was quite enough. The problem is not that it's not strong enough (trust me: it's plenty strong, but more on that later). It's not that the cock ring feels weird or fits oddly (the cyberskin is actually quite pleasant and the width gives a tight grip). Nor is it difficult to use; the speed dial and push button are very effective. It was the combination of all of these things combined that made this cock ring annoying and cumbersome during sex.

STRENGTH: The cock ring is ridiculously strong, because it uses four round, watch batteries. Four of them. A session. And just for the record: We don't have marathon sex. We have normal half hour to an hour long sex sessions, and the cock ring wasn't even on for the whole time. But it definitely lost battery power afterwards. So the annoying factor number one is the replacement of four watch batteries each time you want to use the device. On the plus side, the vibrations were strong enough for both partners to feel, during penetration and foreplay.

SPEEDS/ RHYTHM: At first the plethora of speeds and rhythms made this cock ring interesting and enjoyable. And then it quickly became annoying and unbearable. You can adjust the speed of the rhythm with the dial and the push button has five different rhythms for you to use. Being able to adjust the speed was great. Turning the dial during sex was a distracting and difficult, especially with a condom (see MATERIALS section). The dial did maintain the speed we set it to (meaning the dial didn't turn with any movement during sex). Having a push button for the different rhythms was also a clever device... only we didn't like any of the rhythms. One was a vibrating pulse; another a vibrating longer pulse. One rhythm was a crescendo of vibrating intensity, which would reach its peak and the repeat. There was also a repeating crescendo of vibrating pulses, etc. Each of which you could change the intensity of by turning the dial. We did not enjoy because the crescendos weren't long enough before they peaked and then they would repeat (starting lightly again) and it was not compatible with our sex rhythm. The pulsating vibrations were also too fast or too erratic to sync with during sex.

MATERIAL: Cyberskin is good because while it doesn't feel exactly like human skin, it doesn't feel too artificial. It also does not smell horrifically artificial like some faux-skin products can. The biggest downside (and this is a BIG one) is that it is a very porous material. It will come covered in a dusting of a powdered chemical to keep it from absorbing moisture in the packaging. WASH IT BEFORE USING. And its best to use a condom OVER the toy. Like over silicone or PVC products its best to use with a water-based lube, because a silicon based lube will start to wear away at the toy.

SIZE OF THE TOY: The cock ring is quite powerful for its size, however, the "Custom" grip effect is achieved by a wide, thick band for the ring. The size of the ring takes away from penetration depth.

SHE SAYS: I was not a fan of this toy mainly because I did not like the vibration rhythms. When we used the crescendo rhythms they would crescendo before I was ready for them to (annoying) and then when I was ready to make my crescendo they would restart at a lower interval. When we used the pulsating vibrations on this cock ring, it was difficult to sync his thrusting with the pulsations. I would feel it vibrate on my clit maybe every third thrust, which just became distracting. I much preferred a steady setting and for that you can buy a less-expensive device.

HE SAYS: The thickness of this cock ring annoyed me the most. Because of its thickness it doesn't stretch much which made getting it on and off difficult and getting it on with a condom was annoying and distracting from the sex. Also, the thickness takes away a good inch of penetration depth.
