Product review (4 stars): Better clip, but use your old screw piece
This part came quickly and has a much better clip to hold the spray arm on. However, the screw piece would not go onto the top of my dishwasher. Thanks to a few other reviews, I popped the arm and clip off of the top piece and onto the old top piece. Then I could simply screw onto the dishwasher, and voila, problem solved!
