I thought I just had to have this toy after reading the rave reviews comparing it to the 110v plug-in Hitachi. Unfortunately, I think my expectations were a bit too high for a battery operated toy.
Aesthetically, it's beautiful. It has a velvety feel and is deceivingly light (weight wise). When you power it on in your hands, the vibrations seem more than reasonable, but in action, it leaves much to be desired. It COULD get the job done, but I've also noticed that when pressure is applied to the tip, it tends to "bog down" or lose power which has led to many nights of frustration. That, by far, is my largest disappointment...the lack of consistent speed/vibration when I need it most.
