Product review (4 stars): Thought it was great, but only lasted 3 months.
Overall great deal, but my water has a slightly less pure thank with the OEM Samsung filter. A small price to pay for the cost savings. (And the slightly different taste was easy to get used to).

This filter lasted about 3 months. I installed it in September, and at the beginning of December, the water started tasting less pure, more metallic. Swapping back to the OEM filter.
