I have a couple of these backpacks, one is a regular carry for my laptop and tech tools bag. I’ve had them over a year, and they hold up very, very well. I did have to buy a sleeve for my laptop as these aren’t really laptop bags IMO, but the space in the bag for other things more than makes that OK.
The only thing I didn’t like is the cheap shoestring zipper pulls that came on the zippers, and fell off soon after. A package of nylon zipper pulls fixed that. I’d rather pay a few more bucks for some better pulls to begin with.
