From Her:
We received this cock ring as a promotional item. Vibrating cock rings are not something I've ever tried or been interested in, but since this one was free, we figured "what the heck" and decided to try it out. I was extremely glad that we did.

Basically, this cock ring is composed of two separate sections: a translucent TPR silicone ring and a mini-bullet. Having had disappointing experiences with mini-bullets in the past, I was not expecting much in terms of vibration power out of this toy - however, once my partner had affixed the ring and we started having sex, I was pleasantly surprised. I could feel the vibrations (albeit, mild ones) all through the length of his cock, even in the head, which added a whole new dimension to the experience. There are a series of nubs on the top of the bullet intended for clitoral stimulation, and although I could feel them, meaning the positioning and design of the toy was effective, I didn't really get anything out of them. Instead, I used another bullet to stimulate my clit, and the combination was fantastic.

From Him:
This was my first experience with any kind of stretchy cock ring, and 'wearing' a bullet during sex. After securing it, I switched it on, and was a little disappointed at the lack of stimulation I received from it. This disappointment evaporated when I penetrated Her and saw Her face light up. This was the main source of my enjoyment though, as I continued to not really receive much from the vibrations, nor get any perceived benefit from the actual ring part either. The switch built into the side of the bullet managed to turn itself off a couple times during intercourse, making us have to stop and fix it. Between that and the somewhat short time scale of the battery life, this is something fun to play around with, but not really intended for repeated use. It's fun to see how a vibrating ring feels, and if you enjoyed it you should probably drop some actual money to get a more durable model.

I'm slightly larger in diameter than normal, and putting this ring on caused it to twist around a little bit. A minute spent getting everything to lay correctly sorted that out, and I didn't experience any slipping, twisting, or unnecessary constriction.

Due to the material, TPR silicone, you shouldn't use silicone based lube with it, stick with water based stuff. The original packaging is similar to a condom pack, in that you rip it open, and you can't store anything in it when you're done. Due to the battery life and design of the bullet, however, this is something that can easily and safely be thrown away after one use. Enjoy it while it lasts.

I remember it fondly, how well it fit, how great it vibrated, and it just makes me wish that it stuck around longer! I'll be picking another one up on my next order.
