Product review (1 stars): Like the previous reviewers
Like the previous reviewers, this is second 3-pack batch that did not fit into the appropriate filter system. Prior replacements from Samsung fit easily. HOWEVER: The suggestions to shave off the first small tooth on the left (both sides) by about 1/4th inch using a small knife did the trick!!! There are three teeth; it's the small left one that seems to be the culprit. Hopefully Samsung engineers will read about their defective replacement canisters for the water filtration systems!!!!
