Product review (3 stars): Filter mounting problem
This is  NOT the correct filter by Samsung! It is an  aftermarket brand that can be made to fit, The problem is with the lugs that hold the filter in place. The correct unit has a "ramped" lug configuration, then a short lug with the leading corner removed, and finally a taller lug that is squared.  I had to remove some of the leading edge to make it ramped and take the corner off the first lug. The filter then mounted easily and tightly. Also, this is the correct part number for my refrigerator.  I also ordered three filters from another filter company and they had the same problem only worse!!  I returned them (also made in China) thinking that if they can't make the outside part correctly how good is the inside?
