There were extra pilot holes for the center support that didn't have screws included.  They weren't part of the instructions either but they would have provided greater stability.  When facing it, the left side of the cabinet assembly has a noticeable gap.  That is due to all the pieces having a bow to them.   Typical Wayfair ease of assembly but the cuts of wood make it impossible to assemble flush. The doors wouldn't close due to the screw heads hitting the adjacent screw heads on the hinge.  To fix this I had to remove one or more door hinge screws.
I would rate this 2-stars but because I was able to make modifications myself I'm giving it 3-stars.  I would recommend having a power screw driver on hand to complete this project.
