I used a Rotadent for quite some time because my dentist practically insisted on it. In the beginning, it was great but after a while, the battery would go dead almost immediately and/or the charger was defective and Rotadent refused to do anything about it. So my dentist said to use any electric toothbrush. It's a shame that the company was so uncooperative because I really liked my Rotadent.
