Ordered two of these as a gift and most of the pre-drilled holes for screws did not match up so we had to drill our own holes.  The dowels also didn’t fit the holes securely and would fall out.  For as much as you’re paying for these products  everything should be exact and you shouldn’t have to do additional drilling or wondering if you’re putting it together correctly and following the directions to a tee.  We only put one together so far cause we don’t even want to deal with trying to do the other one and having most of the holes being mismatched.
