Q: It was a little big for me, but it worked really well until about two weeks ago. And then it just died. Mind you, this is two months after I bought it. I switched the batteries, made sure the ones I put in were working, but I suppose the motor died. I never even used it in water. I don't know about most people, but for $30, you'd think you'd get more than two months out of a vibrator.

A:
Negative
