Me and my entire family (of four) are instant converts, and two of us who have been to the dentist since using Quip Toothbrushes have had great check-ups. It has completely changed (for the better) my brushing habits. My only complaint is that sometimes I brush my teeth in the shower, but the Quip doesn't seem to like that. But I would say we are customers for life!
Bottom Line: Yes, I would recommend this to a friend
