For solo play, underwhelming. Try rechargeable Nipplettes instead.

For me, the vibration is so fine that you can't feel it unless you touch the ****** with your finger--putting the ****** in contact with a hard surface to vibrate against--which defeats the purpose of having a hands-free ****** vibrator for solo play. Maybe if you only want to use this with a partner to provide the hands it would be acceptable, but for me, pretty much useless. (If you want solo ****** vibrators you can actually feel--because they vibrate a hard surface against the ******--I recommend the RECHARGEABLE Nipplettes by Cal Exotics. Just make sure the ****** is pinched between the narrow part of the clip rather than hugged by the rounded part of the clip.)
