Product review (1 stars): Don't buy these for a Samsung french door refrigerator.
Never again.  The holes in the Eco filter do not match the holes in the Samsung original.  This filter leaked all over the place.  Fortunately, I discovered it after a few hours.  Water had leaked in to my bottom freezer drawer and froze.  What a mess.  Despite the high price, I would rather pay for Samsung replacements than be dealing with the mess from these.
