Product review (5 stars): Was a little worried, but these turned out to be perfect.
Wasn't sure what to expect with the more inexpensive filters.  The ones I bought about 2 years ago (I got a set of two) and they lasted the two years and were perfect.  But that brand was no longer available, and this brand had the best ratings for this ilk.  Put it in a few days ago, absolutely no problems and the water tastes great as does the ice.
