I already have a PC bag. It is well, it costed me not cheap, but, but, it is right size for my Macbook Pro 17-inch. It is robust, my bag, but poorly padded. I wanted to best protect my MacBook Pro, and therefore this package seemed the best compromise. Already, she carries slung no problem, then it is fine, and finally, it is specially designed for the MacBook Pro 17-inch. The specific pocket is padded MacBook Pro from all sides, with a very high density foam that perfectly absorbs shock. I have not dropped the case with the computer in it, but the foam is very rigid and very robust. It closes further on top to completely isolate the computer. Annexes pockets are very well studied: in addition to the computer, I can arrange it by a mouse (not great either), AC adapter, my graphics tablet, the stylus that comes with it and also a notebook. This is quite respectable.
On the exterior, the finish is NICKEL, sides and bottom are sealed and buckles are metal. Worth a price, but the degree of finish and durability and protection are indeed present.
