Product review (1 stars): Whirlpool Upper Wheel for Dish Washer
Product arrived quickly and appears to be an exact replacement of the original.  It was easy to install and worked well at first.

The top snaps broke within a couple of weeks and allowed the rack to drop again.  The originals broke at the same place but at least they lasted a couple of years.  This replacement only lasted a couple of weeks. Ultimately I slapped a couple of twist-ties around it and the rack to hold it firmly in place.  So far the cheap plastic of the twist-ties has lasted months.  Design / Material Fail!
