Product review (5 stars): Doing its job
So far, so good.  No leaks and water tastes fine.  Instructions say to run a quart or two of water through after installing to flush out air.  A little air will probably get in the line when the new filter is installed and cause a sputter at first, but running enough water through system should fix that issue.  Much better value than the "brand name" filters.  Where I live the water is excellent but changed the filter primarily so my refrigerator would stop nagging me!!!
