Product review (5 stars): Super Easy
This part totally fixed my leaking Maytag portable dishwasher hook-up.  At first I couldn't see the retaining ring because of soap build-up, but once I got that off, the hardest part was keeping the new "teeth" in place.  Otherwise, it was super easy.  Took me about 10 minutes because I kept dropping the teeth, but could only take a few minutes for someone who is more mechanically inclined.
