Product review (1 stars): Junk -- With Photo Of Said Junk After 2 Months of Daily Use
I purchased two of these units, and they lasted less than 2 months.  The original Whirlpool/KitchenAid units, lasted 5+ years.  I don't know how anyone can believe that these are great.  First of all, they only lasted 2 months and I had to purchase new units.  Secondly, they are 3D printed parts, not even molded, OEM parts.  Each of these units broke in different locations.  The first one's axel broke on the wheels, and the second one broke where the adjuster allows to raise or lower the top rack.  Do yourself a favor, and buy the original parts from Whirlpool.
