I’ve had my toothbrush for a year and it’s been excellent. After a blip at first with a faulty battery that didn’t stay charged, it was replaced without hassle. My new toothbrush keeps the charge for weeks (at least the 6 weeks promised) and maintains full strength until it runs out. It took me a while to get used to the narrow head, and to learn how to rotate gently while using it, but I get a really good clean when I do that. I have very limited energy due to illness, so it’s great to have a brush that gives me a good clean with minimum effort. I can even use it in bed - keeping my mouth closed ensures no splatters. I just bought one for my husband and he’s very happy with the good clean it gives.
