Had a little trouble understanding instructions in the beginning (put it together upside down) once I realized the cross bars would not allow attachment.. once this was figured out putting the second table together was a breeze!  It doesnt feel as tightly put together as I would like (and all screws have been tighten well) but will do.  Absolutely LOVE the charging outlets and plugs on top.  Makes it super convenient for charging your devices. Overall happy with purchase!
