A: I can confirm, I own a 7505 and this fit perfectly.

**Q: People are saying the new 30b being shipped is a different design as the old and not as good. Can anyone confirm this? I'd love to see a closeup picture of the new design so I could verify the design actually changed.**
A: The new design falls apart. It it is all one piece which pulls out on one side leaving nothing to reassemble. The older ones each side popped out so between 2 Old ones you could assemble a working unit.  Donot buy the new one. Broke right away.

**Q: Does this product fit the Braun 7526 razor?**
A: Yes. I have 3 7526 models. Unfortunately only one of them Stil works. I have this product on a dash button being delivered every other month.
