After about 2 years is slightly torn at with the original shaving foil, which is why I was looking for a new one. I decided also the same for a new shaving head, because the old has probably done his job. I use the shaver every day, as you can in two years to invest again ... While standing on the old shaving head that I should use only parts 20S, advised me the service of the new Braun 10B Series to take for my 190. The 20S spares no longer exists well. The foil has a new design with regard to the structure of the holes. So are not like the 20S films only holes in the foil, but geometrically arranged structures. I myself was thus able to see any direct improvement but. The razor shaves now indeed feeling better, but I guess that is also mainly to the new shaving head.
Although the price of this combo pack which complies with half of the original price of the shaver of two years ago, I rater to purchase because the shaving performance has increased significantly.
