Product review (5 stars): Good price, good product
I purchased these as a replacement for the filter that came with the Samsung fridge we bought in early 2011.  I was reluctant to purchase an after-market product for something that I really depend on but decided to give it a go.  It was a good decision.  I have used the product for over a year and a half and have no complaints about the clarity or taste of the water or ice.  It does what it states.

The only odd thing about this filter replacement is that I have an annoying drip from the cold water dispenser that only disappears after a large volume of water has been run through the system.  I don't recall if this occurred when I installed the original Samsung filter but after installation I have to run about 3 gallons of water before it stops dripping.  Since this is only an installation issue it doesn't bother me much.

Overall a very good product at a very good price.  I'm buying another set now.

Feb 2017 update.  My experience remains good as I have used these filters for five years now.  I still run a large volume of water through the filter after installation to eliminate air pockets and dripping from the dispenser.  I have noticed a degradation in the water flow rate with the filters purchased in 2015.  The documentation states .5gpm but I am closer to half that rate.
