One shot wireless silicone vibro ring - vibrating penis ring by Cal Exotics - review by cum here

This stretchy rubber ring fits over any size cock. Stretch it and place it at the base. For most positions you will place the vibrating bullet part facing up. As he thrusts in all the way, the vibrations will tease and engorge your clitoris. To turn the vibration on, there is a small switch on the side on the bullet. It is easy to turn on, if you want to wait to turn it on until the right moment.

Seeing as the majority of women do not have an orgasm from penetration alone, this love ring can give you that extra oomph to bring you over the edge during sex. It's hands-free, allowing you to do other things with your hands instead of rubbing your clit.

It has great vibrations that can even be used alone. I enjoy just holding it against my clit. It can also be slipped onto a vibrator or a dildo, and used in the same way as partner play. When slipped on a vibrator I enjoyed having the vibrations inside, from the vibrator, with the heavier more direct vibration of the ring. When done I simply clean with toy cleaner and put away for the next play time.

My male partner could feel and enjoy the vibrations. The ring is very stretchy which means it will fit any size penis. It also means that there isn't that added benefit of a delayed orgasm for him, as there is with some cock rings. It just doesn’t apply enough pressure. Through lots of uses the ring never broke, but eventually the battery died and it seems to be a throw away item. I don’t care for disposable items. It seems like a waste. For the price I would prefer something with a changeable battery. Any cock ring (sorry, ‘love ring’) is worth adding to your collection if you don't already have one.
