I've cut my beard with a hair trimmer from Philips and its battery was unfortunately now flat. Therefore, I have decided after intensive search for the Braun Z6. After the first use I have to say that I was not disappointed, but I'm also not thrilled. The device is working properly and also cuts relatively clean. I have decided to use a length of 3mm and there are probably also become ?! ;-) One disadvantage I feel, however, that the attachment wobbles a bit and I have to say, unfortunately, is in the processing of money been saved verdict after first use:? Device and function ok, material quality current = 4 stars!
