Most vibrators that I've used tend to make my girlparts go numb, but not this one. Mona 2 has six different speeds/intensities and 8 different vibration patterns. There are enough options here to satisfy pretty much anybody. It pulses, it revs, it vibrates constantly, and it does these amazing random patterns that blew my mind. Not only is Mona 2 a beautiful piece of technology, but it also works really, really well.
