I know that the philips sonicare toothbrush with uv protection is a great product, but the only problem I have to say is the vibration of the toothbrush. I can hardly stand using the toothbrush because it bothers my teeth and gums so much. It has a sensitivity mode, but even that is a little harsh. I go between using a manual toothbrush because I cant stand to use the philips sonicare toothbrush to much.
