Product review (5 stars): I'm buying Bosch next time.
What a disaster of a part - DESIGN FLAW! And KA warranty support says this is a *cosmetic* part, and is thus not covered by warranty! Cosmetic!? Like lipstick? This part is what allows the upper tray to slide out! It sure as heck doesn't make the dishwasher any prettier! Thank goodness Amazon has these on Prime. The five stars are for Amazon, not for this awful blight of diseased plastic spoor.
