Product review (3 stars): First couple worked perfectly, the latest one doesn't fit/seat correctly.
I have had 2 filters work flawlessly with my Samsung refrigerator, but the last one just wouldn't thread and seat in place.  The only difference that I could see was that the latest one had two O-rings vs only one on the filter that I was replacing.  I am hoping to exchange it and see if the next one will work.
