These shelves are definitely cheap, but the cost reflects that. For the black option, the shelves are wrapped in a vinyl material, which makes it look particularly cheap. They also smell bad when you first take them out of the box. One screw simply would not go into one shelf by hand, I had to use a drill to force the screw in before being able to tighten it by hand. There are quite a few roughsharp spots on the metal frame that I may try to sand down. 

Overall, I just needed a cheap shelf to use as storage in a temporary space and that’s what this is. They seem sturdy enough. The overall look would be much better if the shelves were metal or real wood, but they work.
