We bought two of these for our office. We built both in a few hours without much issue, however one of the tops was damaged.  Called support and they are sending a replacement top, no questions asked which is great but shipping is about a week out due to its size. 

We also noticed not all holes are pre-drilled and we had some "alignment" issues with the drawers.  It's working "good enough" after a few adjustments, but it's a little disappointing it wasn't engineered to be a bit more "idiot proof".

Overall, we're happy with the purchase and would recommend but with caution.
