Product review (2 stars): ... instructions are poorly written and picture quality makes them useless. However
as stated in other reviews the instructions are poorly written and picture quality makes them useless.  However, assembly is not difficult.  Assembled and installed parts in about 45 minutes but when I tried to put the rack back in the dishwasher one of the rollers fell off.  Evidently it was tightened too much at the factory and the nylon was stripped out.  Back to square 1.  Haven't tried to buy just the roller yet for the replacement part.  It is held on by just one screw so it should be replaceable unlike the original design.  If it is available as a single item at a reasonable cost I would rate the replacement assembly at 5 stars.  If not the entire kit was a waste of money.
