My vibe takes 3 double-A batteries. When I put fresh batteries in it for it's first voyage, I don't remember it being this much VA-VA-VOOM, but maybe I'm mistaken.
Has anyone else had this problem? How did you get used to the intensity?
(Off topic: Does the word intensity conjure up Lost In Translation movie quotes for anyone else? "Turn. Look in camera. More intensity!", lol.)
