I, who was impatient to receive it, I am unfortunately very disappointed. I have a MacBook Air 13.3 "and I expected to receive a truly transparent shell. But it was not and I confess that fixing the product on the computer is poor. The aesthetics Hull only allows to see the apple of Apple shine, and I can not find the material pleasant to the touch. It is much more receptive to fingerprints, dust and leaves fall below the hull. After a week, I plan to order another one that will reach, I hope, my hopes. Of course, this comment is subjective :) x
