Product review (4 stars): The only one that worked for me
I went through about six different water filters from various brands trying to find one that would work for my four year old Kenmore refrigerator on my last refill.  Up until that point I had been successful using 3rd party filters.  This time there was a change in the design for the filters by all manufacturers.  Each one would fit fine but I could not get any pressure at all, just a hammering sound.  This official Whirlpool filter worked right away, producing better water flow than I have gotten with any of the other filter manufacturers.  I didn't notice any difference in the taste of the water.  The filter was troublesome after the first night and I had to adjust it a few more times before it was just right to keep the water flowing.  No problems in the month since.

I knocked one point off since it is a little pricey.
