Product review (1 stars): As everyone else here noted the part on your dishwasher ...
As everyone else here noted the part on your dishwasher is faulty and the replacement part is faulty.  These will break again in a matter of months.  I am going to buy one new set (both sides) reinforce the new set with epoxy and I am going to modify my already broken by another means.  If you don't want to be replacing these things all the time then I suggest everyone who reads this to do the same.
