I live overseas and travel to/from frequently. I use these regularly as luggage because they are lighter and less expensive than an average suitcase and they're more difficult to crush. Overall, they perform well but there are several issues. Just about every time I travel with multiple footlockers I lose a handle off of one of them. The side handles really don't hold up and pop off easily. I have also had a few of them crack along the crease at the clasp preventing it from closing very well. The biggest complaint I'd have is that the lid doesn't close well. It's not even close to sealing around the top. If there's anything small inside, it'll come out. If your bags are in any kind of wind, dirt, or water...anything inside will get wet/dirty. I have overcome these issue by putting the contents inside space saver or ziplock type bags. I also never travel with these without 2 luggage straps which are connected over the existing clasps. So, even with the poor clasps, they tend to remain shut. If you're looking for a cheap, light weight alternative to travel with, these will work. But, if you have high expectations, you'll be let down.
