The bag is designed for the MacBook Air 11 "late 2010 a perfect fit. From a processing perspective, I can not agree with the review of ML. In my case everything is where it should sit. Very handy, I find the front pocket. Here the MagSafe and other small items like USB sticks to find their place. Initially "müffelt" the bag a little. The smell is but quickly disappeared. Well, I think the incorporated "lip" in the bag enclosing the Macbook firmly and again provides extra protection against the zipper. If the bag buy at any time buy back!
