This honestly is a pretty nice little toy, especially for the price. Since it takes a AAA battery, you don't have to worry about it running out of charge, and it is waterproof so you can easily clean it and don't have to be concerned if it gets wet for some reason. It is quite powerful, but not necessarily as quiet as one might hope. Due to its size, it can easily be put into a purse or otherwise carried so that it can be used whenever you want.
