My Oral B 7000 Black is now a year old and halbers battery power only enough for 2 days, a real let down. For the long charging time of up to 24 hours Braun should equal beipacken a spare toothbrush, the whole has nothing to do with engineering which is rather black-clad electronic waste. There was also no lithium-ion battery built in, resulting in a product in this price range should be the standard now. The Braun was once a company with an international reputation and I'm really shocked by this quality loss, you have to pay dearly. This toothbrush is the asking price not worth this battery power is to excuse one cheek and with nothing. Although this is still a case of warranty, the trouble is tacitly left to the customer here, because as I have stated in various forums that abound complaints about the poor battery performance. Unfortunately, you still assign a star, but actually this toothbrush is not a single value.
