Let me say this first. It is NOT a small toy. It's actually fairly large two fingers wide at some points. Not necessarily something I want to complain about, but something to be aware of if you're new to this kind of thing. It's built well, has good weight to it, and it doesn't rattle when its on. It's actually very quiet. Way quieter than some of the straight roommates toys for his girl. The app is nice, it's the Joyhub app. It would be nice to be able to change the speed of the trusting, or intensity of the vibrations, but at $3X I can't complain.
Every guy needs one, and the willingness to try
