My Apple leather case is getting pretty scuffed up. Not sure I'd recommend it anymore based on my experience. I just have to be happy that it's the case getting scratched (and little strings of leather now peeling off) rather than my phone...
No idea about it, but I did see an Anker case with screen protector come up on Facebook the other day. I have had excellent experience with their power products and would probably not hesitate to buy a case from them sight-unseen if I needed a case (and at $15 right now, it's almost cheap enough to throw away if it's not good).
