The Mona 2 has six different vibration modes, lasts for two hours on a single charge, is fully waterproof, and made with high quality body-safe silicone and ABS plastic, which are both latex- and phthalate-free.
Promising review: "I was immediately impressed with just how it felt in my hand when I opened the box: very sleek and soft. Even though it's solid, it doesn't feel hard like other plastic toys. It's difficult to describe. After immediately charging it, I was stunned with how high the vibration intensities get. It obviously doesn't get as intense as the Hitachi (which I actually call the jackhammer of vibrators given its intensity), but it was close enough to actually make me orgasm externally. This is huge for me! What a happy medium: it's strong enough to actually make me orgasm, but my clitoris doesn't feel like it just took a beating. And if anyone else out there has ever used a Hitachi, the very quiet sound this toy makes a world of difference! Now my neighbors can't hear me through my thin apartment walls!" —Genevieve Lynn
