With so many negative reviews I was skeptical at first. Then I began the shaving head and the razor blade and was initially disappointed. I wondered if shaving was now so much better with the new shaving foil and the new blade. The next day I put first the old shearing blade and the old blade back and shaved with it, then I cleaned the shaver and exchanged old against new. Then I shaved again and then I saw what the new blade managed. The difference was clear. In addition, shaving with the new material is much faster. You only have to shave over it. Next time I will not wait so long again to the exchange ...!
