in the looks department - 10/10. it's barely detectable, super super thin, and feels great. it should protect against a drop provided that the phone does not land angled toward the front - there is basically no protection on the front at all. drop it on its face and you're gonna get a scratch. so 5/10 for protection. don't get this case if you're actually trying to protect your phone from most types of falls.
it'll work for me, because i rarely have an issue with dropping my phones, and when i do they seem to always land angled toward the back. plus the gorilla glass seems to be really tough. that said, if i see a similiar case that has more of a lip, i'll snag it in a second.
