The desk was shipped with a crossbar (the piece of wood that runs below the glass and is attached to both legs) with a metal bracket on one end that was not cut correctly to allow for connection to the leg.  Specifically, there are holes in the leg that are 1.25 inches apart and the bracket has to be the same - instead, the holes on the bad bracket were 1.75 inches apart (so you can't run a screw through them both).

I am waiting for a replacement.  May increase to 4 stars if the correct piece comes next week.
