Product review (5 stars): Best purchase of the Year !
Put this on my frig was extreamly easy. I did not even need the other stuff in the box. The frig is over 25 years old and I have always gone to Sears to get the new valves like every 4 years.  Sears charged 4 times the cost. This unit actually moves more water from the cup fill than the other valves ever did.  The ice tray is now always full and not half full.  Best purchase of the year!
