Product review (5 stars): Solid, legitimate Samsung product that works well.
First, always buy something as important like this when it is Sold by Amazon to avoid getting fakes or ones that do not meet advertised specifications. I have always done this over the years and have been very happy with what Ive received.

This filter fits perfectly, works well, and doesnt leak. The quality of the water is noticeably better after swapping out a filter, so its obviously doing something!
