I was given this brush by a Sonicare rep at a American Dental Educators meeting - I'm a dental hygienist who works as staff in a part of a dental hygiene program. I have to say that I was skeptical because I have always been an Oral B Braun girl. But, I do like the Sonicare and use it everyday. The features that I like on this brush are the quadrant timer and the UV sanitizer. My teeth feel so much cleaner after using this brush than when I use a manual brush!
