Shortly after buying my Bwwertung would certainly have been top, but because of the extreme short life is not the case. After only a few weeks, I have the toothbrush complained for the first time since the cleaning performance significantly ran after. And shortly afterwards I had to complain again because the toothbrush during cleaning operation repeatedly faltered / ran. Super was the customer service, who exchanged quickly and now the third complaint (again poor cleaning performance), they have also offered to admit me the money back. For customer service 5 ***** For Langlebigekeit a single *
