Also I need the 1-star ratings Connect. We had now 2 hand parts and each went shortly after the 2-year warranty period 'broken'. Properly broken hand parts were not, but the batteries ran for 2 years after abruptly. And we have the hand parts loaded exemplary, not placed in the charging station after every brushing. And of course, the battery is not exchanged, it is supposed to constantly buy new Oral-B devices.
