I'm currently using these on the upper shelf in my spare room closet, and they are great! They hold a ton, are sturdy enough (if filling with heavy things and then lifting up to a tall shelf, use caution ... they're not THAT strong!), and keep things accessible and organized. I love that they can collapse into a smaller footprint, to store if not in use (though I will probably just keep them in use!) Great value for the price.
