Query: It's fine. But I wouldn't buy them again.

Assembly was fine and they fit well on the bed. As others have stated the drop-down, hide-away function isn't that great. The washers are made with soft aluminum (or whatever metal they are); they are easily bent and twisted out of shape. Once this happens, you are done for. They will never work well again. On top of that the pins meant to lock the rails up have a spring mechanism that tends to come through the holes and need to be fiddled with.In the end, mine don't work properly and are no longer 100% reliable. I keep them in the up position and have them permanently secured with wire...just in case. Unfortunately, there aren't many other choices out there.
