Good price. Seems sturdy and looks just like the pictures. Difficult assembly due to a bit inaccurate instructions. However I was warned and the instructions did not slow me up. The real problem is that you need to have 2 flat edges of the multisided nuts to line up in order to mount the plastic caps. 

One, the nuts are not that accurately machined and the edge thickness varies. Two, there's some extra plastic extrusion on some of the edges of the plastic end caps. 

The fix: I lined up the nut edges as best I could, then buffed down one side of each of the 2 end caps per corner until I could get them to fit. You still want them touching each other, as the friction keeps them in place.
