Bought two of these on sale - thought we'd try it for the hell of it. We were impressed with the vibrating part of it. For such a tiny thing, it packs a wallop!
While lube is recommended, the rubber part was rather flimsy and stretchy so when the lube was kinda rubbed away, there was no need to reapply nor did my partner felt pain from it tangling in his pubic hair.
We also applied it to a different body part while performing oral sex that was great. The only thing I would not recommend it for is to stave off an orgasm since it's not very tight.
Also, if you're having a bachelorette party, it's a great bag stuffer. Pun intended. :)
