Product review (3 stars): Installation/fit is terrible. Filter works well and is only option I can find for NSF 53 filter.
Filter seems to work fine but the installation/fit issue is crazy. I had do trim tabs off with a knife like others have posted - totally nuts that Samsung screwed this up.

I had the original when I purchased my fridge but then switched to an alternative one because of cost thinking all the filters are the same. But the alternative seemed to slow down flow rate pretty quickly AND more importantly, it was not NSF 53 compatible so it didn't filter out stuff. This filter is NSF 53.
