After a few other electric toothbrushes I landed at the Sonicare and have it now already about 3 years. I am surprised anew again and again how thorough the cleaning performance. My teeth feel after cleaning much smoother and cleaner. As for a professional dental cleaning. The various "cleaning programs" and the timer round my ex very good overall impression. Added to this is the super Philips Service. My brush was broken about 2 years ago and was completely replaced by a new bureaucracy. My next will be a Sonicare again.
