Review (5/5): no pulling - just like when the razor was new (but I had forgotten ...
Initially, I thought Braun was pushing blade replacement as just another way to make money, but the old blade set eventually broke and I was forced to get new ones. What a difference they make! As the old set wore down, the shave became harder and took longer - and was more uncomfortable. The problem was that it happened so gradually, I never really noticed it. The first shave after the new blades were installed was a revelation - smooth, no pulling - just like when the razor was new (but I had forgotten about). If you have a Braun with old blades, changing them can make a huge difference in comfort and performance.
