Not only does the product do an excellent job of cleaning and polishing teeth, the instructions that come with it have changed the way I brush my teeth for the better. My first check-up after using the product for about a year (I hadn't had my teeth checked or cleaned in close to 3 years at the time) was perfect and the dentist commented that "whatever your hygiene program is, keep it up because it works on both your teeth and gums." Second check-up, this time with a different dentist, was also perfect with positive comments from the hygienist and the dentist. I am a Quip user for life.
Bottom Line: Yes, I would recommend this to a friend
