Been using this bag several weeks now and have been pleased. The layout engineering is top notch, you can access your laptop, mouse, & charger within seconds & there is plenty of room for a packed lunch, light change of clothers, and lots of books.That said, this is a commuter bag, don't expect to do any rucking or outdoorsy stuff at this price point. The materials and zippers are sturdy but not built for abuse. It won't fall apart on you but would definitely not hold up if repeatedly exposed to the elements.One livable flaw which I have seen other posters comment on; the zippers for the main laptop compartment can and WILL give way if not positioned properly, allowing the whole bag to flip open and potentially spill whatever is in the tablet pocket. The laptop itself is ok when this happens since it stays upright on your back while the rest of the bag clamshells backwards in an awkward/embarrassing position (and always at the WORST time). The key is to never position both zippers at 12 o'clock and instead leave both of them at one of the corners, then you will not have this problem. It would be nice if there was a warning for this but it can be easily avoided through conscientiousness and a minor change of habit.All said this bag is sturdy and hard to beat for for weekend or business travel. The blackout version is also fairly discrete and does not scream to everyone "EXPENSIVE LAPTOP INSIDE!!!!" Highly recommend.
