Best toothbrush out there. Performance/Cleaning I have tried a few electric toothbrushes, but this is by far my first choice. It leaves my teeth feeling cleaner than any I have tried. I recently married and my husband had one. I thought all of them were about the same. No so. I will never go back to the old type I was using. This little gem has an auto shut off so you get a full two minutes of bushing without having to time yourself. At first I thought two minutes with this thing going at such a high speed will be hard to tolerate, but the time passes by quickly after a few uses. I can't say enough about this toothbrush. Love it. Durability As I said earlier, my husband had one. I read on the internet that the average life of the rechargeable battery is 2 years, my husband had his for almost 7 years before it finally went kaput. He swears by it. Nothing else in our home. I hope I can get 7 years out of mine. I recommend this toothbrush to anyone who will listen to me.
