Product review (5 stars): Great product!!
This is a much needed item in my Samsung refrigerator/freezer.  I didn't replace it when needed last time and left it go an extra 2 months and I will never do it again, this must be replaced in the model that I have when the little light turns pink and most definitely red. My water pressure was so low and it stopped making ice cubes, I learned my lesson by not replacing it when needed. Definitely worth the $40 or so dollars it costs.
