Got my case in the mail today. I'm liking it so far, but I'm worried about call quality because the mic hole in blocked. There are 2 holes to the left of the mic, but I'm not so sure how it's going to work. What I DO like about the case is that it is grippy on the sides, instead of being smooth silicone all the way around. The other might-be-negative is that the side door is covered; but that could be a plus as well. The only cut outs are for the headphone jack, and charging ports. The power and volume keys all are covered, but have a raised "button" to press.
All in all, I think this one is going to suit me just fine

EDIT: Nevermind, I think the back hole is a speaker?
