What it is:
- I find very thick shell, so my mac, not the end of the pimps took one centimeter more, which hinder me
- The upper shell (the screen size) was not adapted to the dimensions of my mac (though it is a white unibody 13 inch !!) so that its squealed when I took him in hand, very unpleasant. So I removed.
- By against the bottom, not bad. The air vents prevent overheating during extended use, small pasta to face the computer are very convenient.
However, if for whatever reason you choose to remove the lower part of the hull, good luck! I try it and I have to force, for fear of damaging my mac ... But overall I am still quite satisfied
