Bests & Worsts Reviews from Amazon

This toothbrush is not even close to Sonicare (which I've used since the early 1990's) in performance. I thought it might be better because of the waterspray, which is useful, but the brushing power is not at all impressive. After 4 weeks, I could see where plaque was building up along my gums, undoing years of progress. It's too late to return it, and I hate to just throw it away. Maybe I can try using it on the dog's teeth.
