Had before buying fears (also due to another review) that the sheath only fits perfectly to the end of 2013 appeared (not the latest) MacBook. Apple is indeed for both models exactly the same degree of, another reviewer said, however, the shell would survive in his (latest) MacBook 1-0,5mm. This fear has not been confirmed, the case fits perfectly on the newest MacBook model. Do not know what the other reviewer has done wrong ...
A star deduction there is that no manual is included for installation and removal of the sheath (where best to first press firmly or solve?). With both I had problems because I was afraid of the (necessary) firm pressing of small holders scratches on the MacBook. Property me then ultimately inspired by a YouTube video. Had so firmly closed that I would have expected there were scratches but seen after re remove the envelope no.
