Product review (5 stars): OEM Part performs just as it should
The bottom sprayer fell off during a cycle in my washer and got melted by the heating element, so I needed a replacement, and this fits the bill.  It's an OEM part with OEM fit, so it went on easily, and restored my dishwasher to like-new condition.  Just make sure you tighten the ring when you install it so you don't have what happened to the first one happen to you -- looks like mine wasn't screwed tight from the factory and I never bothered to check.  Instructions were good, and it was an easy fix.
