This assessment I write, after I've tested these blades (a long time) itself. Unfortunately I have to be assessed as satisfactory to poor these blades. The first blade: -hoppelt only over my thick beard and thus was shaving unsatisfactory because mehrmahls had to be painted on a skin site. The skin was highly irritated. Nevertheless, I have further tested (blades were not cheap) The remaining blades could not convince me, because they had no right cut sharpness. Maybe it was just this pack, which had unsatisfactory cutting performance. That can not and I will not try, because that the price is too high for me. For me it is clear that I will not buy in the near future this blade here because I may ask for this high quality high price.
