Every MacBook I've had always end up scratched on the bottom, the little rubber feet just don't keep it high enough off the table. I just got a new 13" MacBook Air so I decided I'd purchase a BestSkinsEver skin just to avoid the scratches. For $20 it's well worth it to me to avoid these scratches. It arrived rather quickly even with the free shipping option. Install was fairly easy, I just wish it can with a bottle of solution since I couldn't find a spray bottle to use. I ended up just pouring it onto the skin and rubbing it around with my fingers which worked just fine. Fit is perfect, all the screws are still accessible so if I need to remove the rear cover I can do it without removing and then needing to replace the skin. Tip: Use plenty of solution, makes install very easy Overall very happy with the skin, and even more so that I can use my MacBook Air without always looking for something to place under it to avoid scratches.
