Product review (5 stars): Same as the Samsung OEM water filter.
From what I can tell the internal workings of these filters are the same as the Samsung OEM filters at the fraction of the price. I installed one the other day and it works fine. Note the height of the replacement filter is 1/2 -3/4 inch taller than the OEM making it necessary to remove the top shelf from the uppermost position to get the clearance needed to get the filter in place.  However inconvenient , its a small price to pay for the huge savings gained over the OEM filters.
