I have been using sonic care toothbrushes for over 4 years now and can honestly say these elite toothbrush heads are the best version to date. They have a flexable neck and small brush head, that allows easy cleaning of hard to reach molars. Very satisfied with my purchase!
Love the Sonicare product- does a great job at cleaning teeth and keeping gums healthy. Too bad the replacement heads cost almost as much as the entire toothbrush system
