Product review (5 stars): Works great!
I had a Samsung filter in my refrigerator and replaced it with this one. Installation was simple. I unscrewed the Samsung filter and this one screwed right in. Before I installed this one, I compared it with the Samsung filter.  The Samsung was a little larger and had a sticker on it, which came in the box, letting me know to change it out in 6 months.  This compatible one did not come with any stickers, but did have a note on it that it should be replaced in 6 months. So far, so good.  My ice and water taste and look the same as with the original Samsung filter, so it appears to be filtering just as well as the original.  As for longevity, I will have to wait to see when the filter light comes on to know if indeed it lasts a full 6 months. This will be interesting to see, particularly since I noted this compatible filter was a little smaller than the original one from Samsung. I will update this review when the filter light goes on to let you all know if it lasted a full 6 months.
