This thing is no joke to assemble. It arrived in 8 or 9 boxes with unlabeled contents, and very poorly written directionsillustrations. Now that it is installed It looks ok, but I’m not impressed by how visible the tracks are behind the shelves, and the composite wood (although heavy) looks about like you would expect. The manufacturing company could DEFINITELY provide better instructions and parts labeling. Even screwshardware is just dumped into bags un-separated. 

I’d give it a 2-star review BUT I like how it’s
Modular and I was able to arrange the layout in a way that better fits my space.
