I had a black plastic case on my macbook air by Topcase from amazon. I wanted to take it off to check my computer for dents and I nearly broke my screen trying to get it off. I tried taking it off different ways and by the tabs but the tabs would not release. I was able to get the bottom off ok but the top was so bad. Im actually afraid to put it back on. watch out of you get this case. its a nice cheap case otherwise. Also there is vents on the bottom despite the air having no vents there. so its just an opportunity for debris to get inside and under the bottom case.
