Product review (3 stars): Perfect Replacement for a flawed design from Kitchen Aid
Not sure how many stars to give a replacement part that is ultimately designed to fail. This is one of the many reasons why Kitchen Aid is not what they used to be. I've replaced this part on two other occasions, on a unit that was installed in mid-2011. In my experience, the wheel clips become dry and brittle with use and eventually snap off, causing the wheels to fall off, causing the rack to disembark from the guide rail. Overall this part is a perfect replacement, so three stars to the seller for offering OE parts on Amazon.
