Product review (5 stars): Order this to make your life easier!
Why they didn't make the dishwasher with these parts to begin with, I do not understand!  After years of complaining about this expensive dishwasher being a POS because of the plastic parts it came with. I finally ordered these.  It make a big difference!  I just hope it last.  Now if they would just make the bottom rack quit jumping off the tracks!
