My first purchase was damaged, so I received a replacement. Turns out that I actually needed to borrow pieces from the broken set in order to fit my space. According to the package instructions, it should have fit 80" easily. Not a single configuration worked, hence why I needed to borrow a piece. After putting it up, I found that the shelves did not stay in place, no matter how hard I screwed them in. I'm extremely dissatisfied.
