This little Black bullet is THE best little button pleaser we have tried so far ( 4 in total ). I thought the cordless expensive one would be top of the list but this one has become her unanimous favorite. My wife says it's just the right size, feel and power for her to have quick, powerful orgasms. Oh...and it's nearly completely silent which is awesome. When the toy box comes out , this is the first one she picks. I may have to express post the replacement if this one ever stops. She won't want to be without it for more than a day or two :)
