After some time in operation, there is nothing to complain about. Only minor complaint is charging. When the toothbrush is empty, needs this good 24 hours up to complete charging. We can live with that but. We only recommend the toothbrush.
Unfortunately, I now have to say use that the battery is not even 20 minutes after about 4 months. Brushing keeps and he now takes almost one and a half days in order to fully charge.
