We purchased a new laptop and wanted a protective cover that would fit into the new carrying case we had purchased. This cover was easy to put on and the Satin finish has a comfortable feel and does not show fingerprints, as compared to the non-satin finish. We were concerned with some reviews regarding cracking of the material during install and after some usage, but we have yet to experience any cracking issues. Quite the contrary. This laptop is used indoors and outdoors on a daily basis, and the cover is still looking great. Highly recommended.
I bought this for when I go camping so that I'm not holding the 11" MacBook Air with kitten gloves when out in "the wild". I was a little concerned that it would overheat because there are no heat vents on the underside (which is why I bought it - so I could pop it down in the tent without worry) but I have to say I am highly impressed with this. So much so that I leave it on even in the house. Doesn't overheat in the slightest.
Previous to having this snapped onto the MBA (it's easy to put on and off and stays securely in place - oh, and doesn't stop the screen from closing all the way like some others) I used to use a rather nice slip case, but now having this on all the time means I tend to use the MBA far more often than when it was in the slip case - in fact I'm using it now.
The surface is a nice matt and is resistant to fingerprints.
I had this as a replacement for the Speck hard case cover which started having small cracks within 3 weeks of use. This Speck product seems more durable than the hard cases. Finishing also seems better. I will recommend this over the hard shell versions.
