They are pretty good in durability it would seem, I haven't had them that long. The downside is trying to get the screws into the shelves to mount them. There isn't much room for your hand, but with the right tool it shouldn't be an issue. I am limited with amount of tools I have in my apartment. I don't have a full handed screwdriver or power drill which would make mounting these a lot easier. But definitely worth the purchase.
