rez821 year ago000is it normal that with the 3708 model when I put it on charge, no light appears to indicate the battery charging status?Show in original language (Italian)tomtom841 year ago • purchased this product000purchased this product Helpful answerHello, unfortunately this is the case with the new model.

The toothbrush lasts about 1 week, then you realise that you have to charge it when the motor starts to run low.Show in original language (German)Commentcatherinedill19656 months ago000I don't like it!
