Product review (3 stars): The first filter I got was fine (11/14). No problem
The first filter I got was fine (11/14).  No problem.  Immediately after I installed this one, the water flow was significantly decreased.  I email Amazon and received a quick reply stating they would  to replace it w/ one day shipping (excellent service!).  In the interim, my kitchen flooded.  Somehow, the filter had caused a leak.  As soon as I removed the filter, the leak stopped.  However, there was a LOT of water before I caught it.  Could have been a lot worse had I left the house.  I will install the replacement and watch it carefully for leaks.  That should NOT be needed.
