Product review (5 stars): completely satisfied
I have been drinking the water from my well for seventy years , so the filtering of the water going into the refrigerator was not too important to me.  When,  after two years, the cold water stream from the door had slowed considerably; I was appalled to discover a new filter was over forty dollars.  The Sentinel filter was the perfect solution.  It fit and worked perfectly.  I would recommend this product.
