Guides were bent which made assembly exTREMEly difficult.  Also, a washer was missing from the kit.  But here's the best part... there was a giant glob of whatever they paint it with on one of the rails.  I went to lift it off and it smeared everywhere like tar.  All over my hands and wouldn't wash off with soap and water.  Left a big unfinished metal spot on the rail.  Now I see why this item was so deeply discounted.
