Product review (5 stars): A lot less expensive than a new refrigerator.
This is an easy part to install.  There are three screws and a four-wire connector.  The connector is hard to detach and attach, and the screws must be managed by feel with a nut driver.  When installing, remember to put the fill hose through the hole designed for it before inserting and tightening the screws.

This is the second or third one of these I bought.  So why do I rate it a 5?  I still haven't spent the amount needed for one repairman visit.  Also, I think I damaged the previous one.  I had not replaced the water solenoid first, so I was hand filling to produce ice.  I think I was overfilling because the clock mechanism filled with water and froze.  That can't be good.  If you are hand filling, go easy on the water.
