Very poor quality. The finish is nice enough for the price, but the thread inserts are the wrong way of fixing such thin particle board...mine pulled out at the first attempt at assembling.
The metalwork is very flimsy, too....good job nothing heavy is going on this.

A footnote: The Wayfair site only has 2 options if there is an issue...return full product or partial refund.
In my case what was needed was a replacement corner shelf
