I already have low expectations when I order pre-fabbed, DIY furniture, but these shelves managed to go lower than low.  One of the metal sides came with a screw hole that was not drilled through properly, basically closed. I don't have a metal drill press at home so... idk what I'll do.  Pound it with a nail & hammer??
A few of the particle board 'wood' parts came with scratches; one shelf piece was all black (didn't have the fake grain paper on it); and the fake grain paper was peeling off at least two shelves. Most humorous was the black touch-up marker strokes the Chinese manufacturer used to cover the aforementioned scratches. Very evident and unsightly.

Pros: Look nice from a distance?
Cons: not a good value when you can't finish due to poor quality control
