Product review (4 stars): Easier to Install than Other Reviewers Described.
I am giving it 4 stars because I think it is a part prone to failure.  My teenagers begrudgingly do dishes and despite having a $700 dishwasher they thinnk they can slam everything around.  So the fact that the first part broke in about a year. I don't have high hopes that the replacement will last long.

The part was easier to replace than expected. I paid careful attention when removing the broken part and the new one went in a SNAP!
