Product review (5 stars): As good as SAMSUNG but CHECK THE ALLEGED WATER LEAK SOURCE FIRST BEFORE BLAMING THE FILTER
Works as well as the original expensive Samsung filter,  The reported "water leakage" noticed on some of the reviews is probably due to what happened to mine when I did a swap with an authentic Samsung filter,  When I had the service contract tech come out he showed me immediately the culprit---a blocked drain line from the inside drip pan catching any small leaks but MOSTLY the condensation buildup in the refrigerator and drains it down to a large evaporator dish under the freezer compartment.  He stated my 2 year cycle was about right for it plugging up.  The solution was to simply pull off the 12 inch laytex tube and clean it out with compressed air and clean water.  So before you blame the filter check that drain line on the back of the model from that inside pan to the catch pan that evaporates the condensed water in the bottom of the refrigerator. It would have saved me fifty bucks throwing away a perfectly good filter,
