Query: NOT POWERFUL ENOUGH.

My main method of play is a personal mini massager...I'm lazy and it gets the job done.This one does not have the peak full-battery power that other ones do. I had a Hustler one for a long time, it worked well. A friend gave me a couple cheap white ones. One worked well, the other had a technical issue.I'm still looking for that perfect mini. I'm not looking too hard though.
