Product review (5 stars): Super easy to install (look up on youtube)
It came with the plastic nut that is not supposed to break but often does.  I found a part in the bottom of my dishwasher, but easily matched it to this part and found instructions to repair this on youtube.  I am not handy, but easily did this repair.  I did it without tools as my washer's water supply tube clips in.  Other brand names' washers use screws.  For $10 I saved the cost of a repair service or even replacing the washer.
