Zagg Rainier?
I was won over by the drop protection (22ft), and have dropped mine (3~4' onto carpeting a couple of times, 5' from the dresser top) and it's been "so far so great!" in that area. Not an issue here either.
I've yet to remove the phone from the case to verify anything after accidentally whapping the phone's side edge against the bookshelf's shelf. It wasn't much pressure, I'd reckon less than a 4' drop onto the carpeted floor at a slight angle too, but the hard outer plastic ring would likely have taken the brunt and not dent the phone within. I don't think it had, given the confidence in Zagg and previous drops so far. If I switch cases, since I prefer the beige over the green to complement the blue phone with (beige looks great opposite orange as well), I'll know for sure if there is a tiny indentation by then. Zagg was easily one of the best case makers out there.
