Product review (1 stars): The part is perfect.  The dishwasher blows...
Of course, you already know that if you're looking for these parts.  This is my second pass replacing these brackets in a three year old dishwasher.  It's funny, I always thought Kitchen-Aid (Whirlpool) made decent products - the dishwasher was certainly well reviewed.  Obviously, the people who wrote those reviews never used the dishwasher for any length of time.  Since Whirlpool has made dishwashers for forever, the design of these rack adjusters is inexcusable.  For the 50 cents it would have cost them to make a reliable part, they have lost a customer forever.  Somebody deserves to get fired...
