Product review (5 stars): I'll never pay Sears $50 for a filter again
I have a Kenmore Elite refrigerator, and Sears charged more than.$50 (including shipping) for just one filter the last time I needed a replacement.  I tried another brand a few years ago because $50 is a ridiculous amount for just one filter, but it leaked all over my refrigerator, so I was a little reluctant to try a non-Sears brand.  I was even more skeptical because these filters were so inexpensive, but it turns out I had nothing to fear.  It took all of a minute to take out the old filter and put the new one in.  After a few blasts of air and a few glasses of iffy looking water, all is well in my world again.  My water is fresh and filtered and my wallet is fatter.  I  highly recommend these filters.
