Product review (4 stars): Works as expected.
I've purchased the same filter for my refrigerator a few times a year for the past three years. Installation is easy (though often difficult to twist/remove the old filter) and it works very well until the filter begins to get clogged with use - for us about 3-4 months of pretty heavy use. Would give five stars if it had a more grip-able way to remove it and a longer filter life.
