Very poor quality and even though free shipping to receive, you pay to return.  I've assembled many home office products and this was one of the most low quality products I received.  Holes to not compliment screw threading, very little packaging to prevent scrapes during delivery process, and lengths between pre-drilled holes are incongruent with holes of filing rails, for starters.  I stopped before attempting further assembling because I was already so dissatisfied.  Top it off, they deducted approximately 27% of original price to pay for shipping to return it! First time shopping with Wayfair, last time shopping with Wayfair, and will definitely tell others of this experience.
