I like the feel of the Apple leather case but button sensitivity is reduced a bit too much for my taste. It's hard to adjust volume. The search goes on, I guess. I didn't notice before I took it off that the red case is (PRODUCT)RED (Apple sends part of the profits to fight HIV/AIDS in 8 African countries). For that reason I'll keep it instead of returning it. Heck, if I don't find my ideal case I might come back to this one.
Does your case have the metal buttons? On my Apple leather cases, the metal buttons don't really feel any different than the phone's volume and power buttons. I'd suggest taking it into an Apple Store and see if you can't get a replacement red case that has better button feel.
