Looks very good, well made - and most important in a notebook sleeve: provides the MacBook Air optimal protection. Unscratched the housing and the notebook is well protected against the zipper. Foam material is initially a bit strange, because you can push in dents easily, which then remain well stand a minute before they disappear again. The only drawback (and that's why only 4 stars from me). I deliberately chose this shell, because they - not like everyone else, I could find - exclusively for MacBook Air 13 "is designed and not even for the normal MacBook Had hoped that the shell thereby slightly slimmer fails and fitted exactly fits around the Air. Could for my taste but something closer to the MacBook Air, then the whole would also slightly more compact. The MacBook sits but still firm enough in the envelope and does not wobble around. Therefore, these are just little things - and to get over the price at all.
