I have the device now for 6 weeks in operation and can join my Vorrezensoren in many ways. I find the razor something large and clumsy, he is nevertheless well in hand. The noise is considerable, but can easily withstand. The shaving performance is ok, even if you (more than 2-3 mm) quite often about it must go with longer stubble, until all at the same length (and afterwards one finds then still often a few "outliers"). Accordingly, one must also schedule 10 minutes for a "manicured stubble cut", but I'm as only once a week. But I think that is not necessarily on the razor, but a general problem is, if you do not want to trim at its roots, but with a few mm residual length longer, sometimes curved and tight-fitting to the skin whiskers. Since the blade must accordingly get to grab the hair first. The two different articles with different adjustment mechanism seem in fact to not entirely thought out, but work. The cleaning is very tedious because the cut will disappear in several columns and remove one essay and blades need to Ihne to remove. The battery life can I find so far in order. After 6 extensive applications I had not reload the battery. The specified charging time of 14-16h is however already a thing and can go on a trip to the practical problem (if one wants to avoid partial loads, which is according to the instructions should, in order to prolong the service life). Unfortunately, there seems to be no way to replace the battery. The operating instructions in German language and content leaves something to be desired. I would advise against not by the device, but we can not expect miracles.
