I had the Apple bumper, it looks like absolute crap after a weeks use (white one), and it's "bulky" for someone looking for minimalistic. Picked up a Ultra Case slim bumper, It's really nice for what it is, super slim, no lay on table protection. However, it gets dirty really quick (white again), and the buttons are SUPER hard to push. It really stands out. Chucked that into the drawer.
I just run it naked now. I use rubbing alcohol on it every other week to clean the phone up, looks new like day one.
I like the Desmay case, it's super thin. But I like it with nothing now
