My experience with cock rings so far has been sub-par, but I'm still on the hunt to find one that works for me and my man. The idea of them is great, especially since my #1 turn-on is clitoral stimulation. That being said, we always assumed that purchasing a vibrating penis ring would be the way to go. These are great for the dual stimulation effect. However, the Sex on the Go Power Ring doesn't quite work for us. In theory, it's a great toy. The ring itself is ribbed for pleasure, and the vibrating action is easily turned on and off with a sliding control on the side, but in execution it just doesn't work for us. The vibrations aren't very strong, the ring is far too tight on him, and the ribbing does more to hurt the experience than help it. I'm very disappointed, since I really do like the idea of vibrating cock rings, and I'd love to have one that we can use.

The ring is made of TPR, which is a rubber polymer blend that is compatible with water and silicone based lubricants. It feels stretchy enough, and it might be okay for men with smaller girth. But herein lies the infinitely unsolvable issue with his penis-- it's too damn thick! I can't find a good cock ring, masturbator or any male toy that's thick enough to accommodate him comfortably. If you also have this problem, beware.

The unstretched diameter of the toy is 1 1/4", while the stretched diameter is about 2 1/2". The unstretched circumference is about 3 1/2", which the stretched circumference is about 4 1/2". While it does stretch relatively well, that does not ensure comfort. Within seconds of putting the ring on, the veins in his penis popped out and were very distinguishable. About 30 seconds after that, his penis and balls both started to turn a sickly purple color, so I immediately took it off. If you experience this, I highly suggest you remove the toy as quickly as possible. We don't need to damage any man junk with this.

There is one on/off switch that is controlled by sliding. There are no other vibration options, and when left in the on position continuously, the batteries last for approximately 23 minutes altogether. The vibrations aren't too strong, and are probably better left to those who are sensitive. It wouldn't do much for me used as a finger vibe, since I need something a little bit stronger. The toy can be cleaned and reused, but the batteries are not able to be changed (believe me, I tried to pry the thing out of the rubber case and see, but it's nearly impossible). This is mostly geared for one-time use, I believe.

TPR is relatively porous, so it cannot be disinfected without the use of boiling water. Condoms are recommended when sharing this, so if you plan to share, wear a male condom underneath the ring, and perhaps a female condom to protect the area that will be exposed to it during intercourse. Warm water and soap will wash it, but not completely sanitize it.

The ring comes in a plastic pouch inside of a small cardboard box. The box is white and has green and black print on it. The box is not entirely discreet, but it is small enough to be easily hidden or wrapped.

Personally, I wouldn't recommend this ring for anyone who has a penis with a circumference greater than 3 inches. That being said, if you enjoy pain this may be the toy for you. Sadly, we couldn't use it, and the hunt for a cock ring that isn't too tight or uncomfortable will continue. If you've had this problem and know of a toy that will meet my needs, please feel free to share your discoveries.
