My mom bought my backpack 25 years ago and the clerk told her "they'll last for at least five years".
Well I still use mine daily, so yeah. Definitely lived up to expectations. Although I've did get it fixed, but first time just a year or two ago. So lasted without any fixing for longer than the average age on Lemmy, I'd say.
I sound like a shill but I LOVE IT. Lugged laptops around with oodles of other things, I really like that the top handle has like, twisted wire in it so it doesnt snap off when carrying heavy loads.
Power (not adidas, the brand is power) backpacks are good. Spent like 25 bucks a decade ago and it only needed some stitches. Was daily use for most of that time, too!
I bought a laptop backpack a loooooooong time ago, and still use it constantly. It's been through 3 laptops, and I'm not the type to upgrade until it is absolutely necessary.
I bought a military grade backpack on a Marine Corps base in 2001. I used it for 3 years in the military, then all of undergrad, masters, and phd school. I use it on almost all of my travels, and I use it daily in town. It's still going strong. Hope to get another 23 years out of it.
