Product review (4 stars): Good product, fits properly and installs easily.
My preference is to use a filter made by or recommended by Samsung for their refrigerator, knowing that it's more likely to fit properly and perform as expected.  There are many generics out there that are probably less expensive, but I would rather not take a chance that could result in a water leak and related damage.  It seems to work as intended and we use the water and ice from the refrigerator for drinking and cooking because of this filter and what it's supposed to be doing.
