Very good quality and good fixation

The hull is of good quality and well protects the MacBook Pro, while allowing access to connections and keeping the ventilation openings. It also has soft plastic small plastics in 4 under the MBP to cushion and does not rest directly on the table. The shell is not too thick, even if necessarily on a computer as thin as the Retina this is a good thickness and more.
Unfortunately it is rather cumbersome, and it adds a lot of weight to MBP. Too bad since the MBP also buys for its lightness, but they can not work miracles
