It's an awesome toothbrush...It has so many cool features. Using Bluetooth Technology, it gives real time feedback to improve brushing methods. It has a sensor that prevents from brushing too hard to protect my gums. I really like the several different modes I can choose to personalise my brushing experience and it had my mouth feeling like I'd just came from the dentist. My teeth and gums feel great!! I love it and highly recommend it to anyone interested in maintaining an excellent oral hygiene.
