OK at first
I have had this for a year. It no longer holds a charge. The grip gets filthy really fast. The place where the brush head connects to the handle gets filthy fast also. The bottom which sits on the charger and the charger itself get moldy if you place your brush on it after you brush. You have to let it completely dry, but then it dies and you have no charge for brushing. Some major design flaws.
