Aluminum Pocket check-in, Any issues y'all developed yet?

I think there's been enough time to check in and see how the aluminum pockets are holding up after release. I'm aware of someone showing the sides of their buttons showing wear and tear due to metal on metal friction and oxidating (if I remember correctly), but I haven't heard of anything else. I'm also wondering what would be this version's problem that affects them the same way the colored plastic version had cracks at the corners of the screen.

TL;DR: is your AP okay so far?
