I purchased this on amazon, and was initially very pleased with the product. However, within a month or so, the stitching holding one of the handles in place came undone. And, after about three months of use, one of the hooks for the straps snapped off without warning, causing the bag to fall to the ground and damaging my laptop in the process. The bag was never overloaded - the contents always consisted of one 14" MacBook pro + charger and cable, a mouse, one a5 notebook, a couple of pens, and some emergency medication - so, it would be safe to conclude that the quality and durability are questionable, and I would not recommend this bag to anyone.
PS: I tried reaching aircase for exploring the possibility of a resolution, but their email address and phone were both unreachable, further calling their commitment to their customers into question
