On the first day after receipt I noticed already that the shaving head through the "Release" button is difficult to solve. Depending on the position of the shaving head went the shaving head times heavier and times lighter from, but never knotless like my old Braun Shaver Series 5. Place Also he was somehow sluggish. The button simply did not work properly and could be partly not press properly or only very sluggishly.
After I read the debate in some reviews of similar problems, but increasingly from the "Lock" switch, I tried this for the first time after and really laid the shaving head was through the operation thereof is not. At least not as strong as with my old Braun shaver. When I wanted to try to solve the shaving head in the lock position by using the release button, the determination of the upper part of the razor dissolved the same without that the lock button moved or been moved by me. The shaver head was so freely during the lock button was activated.
Of course, I then checked again and found that the upper part of the razor, is to be determined by the lock button, easily dissolves by itself what should definitely not be the case.
Had the difficult-to-remove shaving foil or the difficult to remove the shaving head was the only problem I would have kept the shaver, but with this clear defect, I'm not willing to pay that price, even if I at least not currently need the lock.
In summary, the apparatus is not worth the money and I have him returned to reimbursement and not to exchange, because I start from a design flaw that should occur with a replacement unit. At least let me other reviews in this belief.
