Product review (1 stars): The generic one I had in before fits fine. a couple years ago i used the samsung ...
they came in quickly, are real Samsung filters.  But it does not fit properly without making some modifications.  If you look at the three key (or ears) the first one is a little bigger than the old ones I have.  I don't know if they changed the design but it would not twist on properly.  The generic one I had in before fits fine.  a couple years ago i used the samsung filters with no issue but now it doesnt fit.  Didnt want to return, Anyway I had to get a sharp blade and trim the first tooth on both sides.  don't cut off completely or it may not lock in place well.  the filter itself works great, I am giving one star because there is no way that Samsung should be saying it fits my fridge when in fact it really doesn't.
