Product review (4 stars): Great replacement for Samsung Fridge!
This is my second replacement filter from Waterfall Filter Company.  It fits just perfectly.  Installs in seconds (assuming you are old hat with knowing how much pressure you can put on the rotation, as it does take a bit of rotation power to get it in place).  All seems well with this one, just like my first.  Only reason it doesn't get 5 stars is that it doesn't filter out the same level of potential contaminants as the OEM Samsung version, but I am not concerned with that as much where I live. If your drinking water is already safe, spend 1/3rd the amount on this one and you will be satisfied.
