I chose this DVD rack to fit a space requirement (width).  I knew it wasn't the most stylish or made with the best materials.  But for screw together furniture, it's the worst piece I've ever bought.  The structure is only 11 pieces of wood, all held together by the "cam connector" system, which is standard today.  In this case, however, the ball/spindle pieces were too large for the cams.  In the end I had to buy metal screw on strips for every intersection to give the unit stability.  Very frustrating.
