I have to admit, I originally bought this just because I wanted something smaller, designed for the prostate, vibrating, and cheap. I can definitely say I'm a satisfied customer, the thing kicks ass. The battery life is crazy good considering it only takes one AA. The first vibration was good enough, but the second setting is not messing around. And for anyone questioning how waterproof it is, I've done my own research in the shower a dozen or so times. It still works quite well.
Only downsides I can point out are, the fact that it stops vibrating with just a little pressure on the button is a bit frustrating at times. And the knobby part at the end is a bit intense on the way in and out, but it's quite effective. It's also a little bit loud especially on the 2nd setting. Even with those gripes, this product is a steal! It's become ol reliable, I'm a happy guy
