Product review (4 stars): Good, Could be better
OK cheap replacement, not as good as original Samsung.  Different purification classification, and I've noticed a slight white mineral buildup since putting this one on my fridge.  We've got super soft water here, so it shouldn't be a thing.  I bought a 2-pack, so will have to see what's what after putting the second one in in a month or two.  Might have been a fluke, but this was the first time that I saw the buildup, and it coincides with the installation of this filter...
