On my old MacbookPro (Mid 2010 15-inch) fit the ultra-thin 0.1mm version pretty much just on the current Wireless Keyboard. On the MacBook Air (Mid 2013 13-inch), the key level is so much lower and the hub lower, the silicone keyboard fits halfway on it but the typing experience unfortunately ugly, you have to beat on any key fairly and then the cover slips is always something. Therefore, 4 stars, is not noted for a really good product to its compatibility ...
