For this protection against slipping out, I can say that it has rather annoyed me. When I open my bag, I want to take my MacBook, and not pull down on both corners of this protective substance. Meaningless for me. Slides in the closed state can not the device, since the bag fits perfectly. So why this protection?
Qualitatively this bag really is the worst that I have ever seen. Starting with the crooked lettering, over holes in the additive against slipping, to loose seams. Was already clear from the first trial and error, that these seams will not last much longer (for that to happen I have found in other reviews).
This case went back!
