The cutting performance of the trimmer is not particularly good, it only comes with the Turbo function well under way (and then the razor is accordingly loud). The problem is that the razor does not cope in the long run, because: On my first device of trimmer attachment wobbled after a few months, the plastic lock was worn. At first I thought it's because I've been through the essays changed regularly. I then get a new device for free. When replacing equipment, I have therefore the trimmer attachment never taken down in order to preserve the catch. After a few weeks using the turbo function however entered exactly the same problem again! You can then still use the razor, but he is then very loud and cuts even worse than usual already. Only if one adjusts for comb attachment to 1mm length, the trimmer head is still halfway stabilized. Not even longer stick through I could fix this thing properly.
In my opinion, therefore, definitely a design flaw, so now comes a new razor ago. Incidentally, I find the device too expensive anyway because the essays are all inferior. The two film clippers are to use for nothing at all, not even tightened around the contours. This I do with nem razor. The detail trimmer nose hair cut short not right, there's the 10 units for the significantly better. Stupid is also no network operation. This is particularly annoying when a body shave, because when the shaver long runs continuously, the warning time is very low before it turns off by itself.
