Product review (5 stars): GREAT PRODUCT!  I WILL buy more!!!
Absolutely perfect for my refrigerator.  It was a perfect fit and at only $13 it was WAY cheaper than what Samsung (or Lowes) wanted ($49-$55).  You can't go wrong with this filter.  Just make sure you run about a gallon or so of water through it when you change it out before you drink any of the water.
