Product review (5 stars): Great Filter
Not that I have much of choice on which filter to buy for my refrigerator.  This one works great.  In fact I wrote the date of install of the first one and it had already been 2 years.  Oops.  My fridge didn't warn me and the water pressure seemed normal so who knows if it really mattered either way.  There doesn't seem to be too much to the filter aside of the hard plastic outside casing, when you get it out of the box.  Sounds like charcoal or the like on the inside.  After you've run water through it, then the filter becomes heavier and feels like your $30+ was well spent.  Of course that's because of the weight of the water inside.
