I bought this bag mainly because of their appearance, but I am not completely satisfied. However, another reason for buying was the fact that you can open the sleeve almost silently, what with my other pocket (velcro) was not exactly the case.
What stands out negatively is the size of the bag. She is a total fall quite large, although the MacBook would fit well with smaller dimensions. Thus, taking this Sleeve unnecessary space, if you want to transport them in another bag. Another point of criticism is the minimal tension belt, which easily enter presses the felt on both sides and the optics slightly diminish.
All in all, I use because of the too large size of the sleeve almost exclusively my Velcro pocket.
