Product review (1 stars): False Advertisement - Did not fit
Purchased this as replacement filter for my Samsung refrigerator.  Spent a great deal of time comparing filters and reading reviews.  I was certain this one would fit; it has the same distinctive notch pattern as current filter.

There was no reason to remove from packaging until the current filter expired, which was today.  Tried to put in new filter, and it does not lock in at all.  The dimensions of the filter also look slightly smaller than the old one.  This leads me to believe it is a manufacturing defect from poor quality control.

Do not buy this filter for your Samsung refrigerator unless you want to play filter roulette.  If so, try it right away so it can be returned within 30 day window.
