I love this case it doesn't add bulk to it, it fits so perfectly sometimes I forget there's a case even on it. I am glad I got this case because I really didn't want to scratch up my 2012 13'' Macbook Air. This case lets the Air's beauty show through, hard to tell by looking at it that it has a case unless you're right in front looking for it. I really have nothing bad to say about the case or it's quality. I am a bit peeved at such a high price tag for a thin piece of plastic however. It's a good chunk of change after all was said and done with tax and shipping it was like $70 outch.
I've purchased this item twice in the span of three days. The first case came in, it fit perfectly, but the bottom left corner of the bottom case wouldn't attach correctly causing this odd cracking sound. So I returned it, ordered another. Same problem! I don't know if both cases have come out defective (which I highly doubt) or if its just meant to fit that way. I'm gonna send it off again, and maybe try a different colored case.
