Review (2/5): Does anyone have the same problem?
I really had a lot of fun for the first month I owned it. Two AA batteries lasted almost one month. Compared with other rechargeable models, this one was fairly cheap. But after 5 months, now, it's so annoying that I have to change batteries every 3 days! How come a toothbrush eats up power so crazy?! I'm thinking of buying a rechargeable toothbrush.
