Was skeptical some reviews were 50/50 good and not good. 
The grey is a nice color, the plastic panes are cheap but easily replaceable if needed with some DIY. The gold knobs holes are terribly drilled into the plastic, so be prepared to use a bit and drill to drill them out. It is very sturdy with minimal screws. The directions are terrible, be prepared to have a lot of patience.  I'm giving 5 stars because it is a good shelving unit for the cost and style.
