Product review (3 stars): Sadly, this is the only option.
This is the only filter that will work with our Samsung refrigerator.  It's ridiculous that we cannot buy another, more generic brand filter.  We've tried them all, and they make the refrigerator make a very loud growling noise.  I give this one 3 stars because it works well, but it does not last as long as it should, and it is overpriced.
