This is a fun toy for someone else to use on you, or to slip into your panties while driving or dining. It's quiet and small. I wouldn't call it powerful, but for a starter or a teaser, it works well. The price is very reasonable for what you get. The outer is very smooth, so if you are going to insert it, hold onto it! Or slip it into a condom or the finger of a latex glove so it can be retrieved.
