Product review (1 stars): Piece of junk!  Cracked and started leaking 30 minutes after it was installed.
BEWARE!!!!  This filter developed a crack and began leaking within 30 minutes of installation.  Water started pouring out of the cartridge and on to the floor.  Luckily we were home and heard it, but I would hate to think what the mess would be like if it were to have happened during the night when we were asleep or when we were not home.  Definitely will not buy this filter ever again.  And I'm not very happy that Amazon automatically just substitutes this product on our Subscribe & Save.
