I enjoyed it as a masturbator, but my wife enjoyed it extremely well on her Hitachi magic wand. It helped turn on her water works! Simply installing the egg to the head of the vibrator by turn it inside out, and letting the speed bumps go to work on her button!
It works and did not break. What else is it supposed to do???
First time using any masturbator. Feels pretty good, gave a pretty intense feeling, and seems wasteful so might get a reusable in the future.
