I had high expectations for the butterfly penis ring, but it did not really live up to them. One partner I used it with was a bit overweight and I believe that significantly diminished the vibrating effect. Also, I would not recommend this for use by well-endowed males because my other partner complained of it feeling TOO tight and constricting, to the point that he could not get off until he removed it. It's worth noting that the second partner was not overweight and I could still barely feel the vibrations, so if that is the main feature you are looking for in a penis ring, I would not recommend this one. Also, if you want to turn off the vibrations, it is awkward and unwieldy to have to stop in the middle of having sex, have your partner pull out, turn it off using the dial base, and then proceed.

I did like the how the nubs felt against my clitoris, but it had to be lined up right and it only worked well in the missionary position when my partner's body was pushing it into my clit. The material was soft and pliable, which is a plus in my opinion because there is nothing worse than a rigid piece or hard plastic digging into your clit!

This penis ring is small and discreet enough to take it with you if you plan on a romantic evening away from home. It would easily fit in a purse without being noticeable. Another bonus is that it pretty much comes ready to use. Just open the package and slip it onto a waiting cock and have at it! It did not have any unpleasant odor like some jelly toys do. It is also pretty easy to care for; just wipe off with a very damp cloth or use toy cleaner. The nubs may get a bit messy and are harder to clean than a smooth toy.
