It works, but there are aspects of the setup and install that could make this better. I ordered it because I have a topper on my truck, which prevents most toolboxes from mounting onto the bed because of where the brackets sit. This seemed like the perfect solution, so I ordered not only this box, but also a box for my old work truck too. And while it does work, installation is a pain because things don't line up well. I'd assume it was just my one truck, but I ordered two boxes, one for each of my trucks and ran into the same issue with both. So when it comes to the long term durability of them, I can't really say. However this is still a good option when you have either a cap, cover or topper on your bed and need something that will mount to something other than the ends.
