Excellent concept and attractive, cool design.  Poor fit and instructions.   The pre-drilled holes in the glass were not the same distance on top and bottom of the ends of the vertical glass.  This resulted in the glass not being aligned with the top and bottom shelves.  about an 1/16" above the shelf on one end and 1/16" below the shelf at the other end. The glass ends should have been flush with the shelves on both ends in my opinion.    The instructions were difficult to follow and were not practical.   I ended up doing my own thing and ignoring the instructions.   I did not return because the fit was a minor flaw and I didn't want to go through the hassle of a return.
