Hey, now I can not much to say, we are a 3Fam. Budgetary our daughter has been an e-toothbrush, and we have only just bought this. Some say it's too loud, I can not say now is OK, hand dling is OK if you get used to it. Compared to the normal toothbrush I can only say I and my wife are satisfied ,,,, teeth are definitely better clean than with a normal hand brush. What bothers me is the really long time to load, but otherwise wieder.vor anytime all the price is really good not even 50euro. From my high since thumb.
