I have certainly been more than 10 years my Braun 5010 shaver and wanted me just to take care of a new, because my Razor is broken. But actually fits this product still on the old. This made me very happy and I could not believe it. The combination pack was reasonably priced and my old cuts again as the first day. If it would still give a 6th star, Brown would this even deserves for long-term support.
