Product review (5 stars): GREAT PRODUCT!
This filter saved us $30.00 from mfg price....I was smart to READ ALL reviews because it stated that if you DID NOT screw it in tight enough it would not have water flow....we put it in and NO WATER FLOW.  took a pliers and tightened it just slightly and IT WORKS GREAT!!!!!!!  will buy again...also important to fill the filter with water PRIOR TO INSERTING
