helps remove more tartar build up than a standard tooth brush [SEP] compared to a regular tooth brush my teeth feel so much cleaner and the vibration is enjoyable as wellthe battery life is great however it seems to take a while to fully charge this is not a problem at all though because you do not need it to be fully charged to use itthe charger base is easy to clean even if dried up tooth paste begins to build up on itas far as replacement heads i went with the they work great and are cheaper than the oral b brand replacementshighly recommend this powered tooth brush
