I agree with all the reviews and you do get what you pay for! This Moshi cover is lightweight, thin but tough. I bought the transparent Moshi and my MBAir doesn't even appear to have a cover on it. All of the ports are open, the vents open and the screen opens freely. It has a good feel to it and the rubber feet at the bottom help immensely when I have the computer on a table. Snaps on easily and stays on tight. I recommend this item to anyone who wants the protection without the added bulk or look of a cover.
