After four years, it was also because finally time for new blades and shaving foil. I have a Braun Series 1 190 s and it fits like a glove. And the black color of the head I personally like better than the original in light blue. From shaving I can only say that it was worth it definitely. Since I once noticed the wear, the had my old shaving head. So if you want to spend the money, you can do it in my opinion still. It is worth it!
