Defective - two of these Xtreme quit working
I tried... twice. But both of these "toy toothbrushes" quit working. In the past I had a great experience with an older Sonicare toothbrush and was hoping for similar quality with this simpler, cheaper and replaceable battery powered device. No such luck. After a couple weeks it just stopped. Phillips was kind enough to replace it but the replacement also failed after a couple weeks. My advise is to avoid the Xtreme and buy the higher price device (or stick to the simple manual toothbrush).
