Very heavy duty and the drawers seem to self close after giving them a push!  One of the drawers I had to remove in order to attach the work bench would not stay on its track because the one rail affixed to the cabinet base was sloppy.  I shimmed it with a washer and now it works.  It was a mfg. defect.  Other than that shipping was quick, packaging good, and delivery driver dropped it into my shop!  Instructions were adequate.
