It has already lasted for a while until I so rightly came and achieved satisfactory shaving results. Meanwhile, I have the part 3 months in use, diameter and film are so ingrained; so much patience you have to apply well. Firmer pressing on the skin leads me rather to poorer results, and you do have to take some time if you want a clean shave. At first, I've resorted more often to my old Braun, now no longer. Would buy the razor again. It is fair to spend more money and has no guarantee to get a better result.
