A big concern of mine has always been the noise level of a toy. I generally live with others, though my current roommate doesn't care much, but I still don't want to use something that sounds like a jackhammer. The Tantric Mantra is a toy that actually made me wait till I was home alone to even try. Even then, the noise level was distracting, which made the toy difficult to use. Combined it with the limited functionality, I wouldn't bother with this product.
