Hitachi overheats and cuts out - it's american voltage not certified here. Lovehoney did their UK safe certified version. It's perfect, in every way!!

Doxi is the best one I have come across, It's very well built and has speed that is phenomenal.
It isn't used on myself, but you can feel the vib through the woman! (I have used several wands even a Hitachi, I would say this beats it though It is slightly heavier - only slightly though)
