this desk is being used by a student. His main reason for wanting the glass top was for it's trendy design and allows him to use a grease pencil on the desk directly when working on problem solving. Wipes off very easy.  No more paper or dry erase board.  Did not install tray as he has a laptop and preferred to keep on desk. It takes up needed table top space and we are looking for a raised monitor shelf. Very heavy and does not slide around too easy.
