The most worrisome problem I had when thinking about buying one for my wife was that it only had two speeds. It only needs two speeds. Me and my wife love this vibrator not only for the "fun", but that it also doubles as a fantastic back massager as advertised on the box! The Hitachi is fairly quiet, but very powerful, in a good way. This wonderful tool has lead to a much more intimate and relaxing night of fun and enjoyment.

As for the material, it is a rubbery material that is easy to clean and provides low friction. The material doesn't add any extra pleasure, but it doesn't take anything away from the experience either.

The design isn't the best in the world as the wand is chunky and harder to travel around with. The ball on the top of the massager is roughly the size of a tennis ball, but much softer. The honest truth is that the design never makes much of a difference so long as the actual experience is fantastic; which is where the Hitachi really shines.

This toy will not work in any kind of water as it has to be plugged into the wall. It has two speeds, normal, and fast. Normal is more than enough to get most people off, while High is much more intense. Even with a high starting intensity, it is very quiet compared to the vibes it gives off. Simply put, the performance of this toy is the best we could find.

For caring for our wand, we put it in a drawer where it takes up a fairly good amount of space. Since it plugs in, recharging is never a problem and the toy is an easy clean up.
