For the first time in my life, I am from a Brown products more than disappointed. I can not recommend the BT 7050. For the first order, the charger was faulty, so back (13) with no refund. Then kan the new charger works ok in pure battery mode lacks a bit of bite, network operation ok, but the shaving head dissolves. If Brown I have never experienced a theater. The manual is more than poor. Sorry but I'm slightly acidic. Addendum December 2014 now used a few times, the shaving head does not lock, clearly a case for the garbage can. But the shaving head now attached with adhesive, then it does not press. For a Braun appliance an absolute low.
