The top board came with 2 Knicks, very disappointing.  Weirdly there was glue all over the boardsbut luckily they wiped off. 
 Also, the bottom center leg holes are backwards ( leg points back) compared to how shelves need to be installed.  I couldnt just rearrange shelving because the hinge was specific. Overall the unit looks good but the quality is a bit of a letdown.
