Product review (4 stars): Good alternative filter!
I purchased a 2 pack for my Samsung fridge.  I did have issues with one in the set leaking when I installed it, but DiscountFilterStore immediately sent out a replacement for it!  I put in the second one while the other was in transit and it worked just fine.  I haven't noticed a significant taste difference from our original Samsung filter, but I mostly run the water through the filter to add to my Keurig.  The part that does make these difficult is there is no marking on where the filter should line up when locked into place.  I found that I can't keep turning it until it stops because then it leaks, even with a good filter.  (With the faulty one, it leaked no matter where it was twisted to!)
