Product review (5 stars): great product at a great price
filter fit perfectly into my Samsung RFG297 Series fidge.  The water tastes just as great as the Samsung filter and the price is much better.  Only regret is that I should have purchased the 3 pack or a few of the 3 packs!  Don't know yet about how long it'll last, but am confident that it'll be close to 6 months
