The assembly (no manual included) however is somewhat tricky. And I also do not expect miracles for 5, but a guide would have been prima ;-)
You have to pick up the black label, then press the Macbook with a transparent film. If you remove the transparent label film should - according to theory - the black sticker stick on the Macbook. Unfortunately this is not so, because the transparent film adhesive is much too strong. In addition, the transport slide was much too small. Really too small. Quasi only half while the overhanging black foil pieces dangled in the air.
For the bad mounting a star deduction.
