I bought this as a kind of emergency solution for the days when everything else is out of power, and I found it incredibly interesting how it had air pressure AND vibration. It is incredibly powerful, especially with vibration. What brings it down a bit is that the mouthpiece is circular and not oval, so it felt a bit wide and the stimulation wasn’t so centered. Additionally, the controls are a bit tricky to maneuver, but practice makes perfect. Definitely nice to have in an emergency or for those days when you need a little extra kick!
