Product review (1 stars): 2 OUT OF 3-PACK WERE DEFECTIVE!  FILTER'S STATED WARRANTY (30 DAYS) CONFLICTS WITH WARRANTY CARD (6 MONTHS)!
JUNK!!!  Just like Brian Shoen's 8/27/16 review, ONLY ONE FILTER OUT OF A 3-PACK WORKED, the other two were defective and would not work.  One Star is one too many!  I am hoping the distributor will not penalize me because in November 2016, I ordered a supposedly "economical" 3 pack back (thinking I'd have a couple spares on hand for later use) but less than 6 months later (after installation of the first filter in February), the other 2 filters are completely defective.  After you buy the filters, you will open the filter and discover it's label states: "30-day Money Back Guarantee" but the enclosed warranty card states "FILTER USE: 6 MONTHS OR 300 GALLONS, WHICH EVER COMES FIRST, WILL VARY BASED ON WATER CONDITION" and "For six months, this filter will provide great tasting drinking water and ice..."  Only one of the filters worked (for 4 months), but the other two are junk!
