Product review (3 stars): Great filter, better then more expensive competitors.
Very impressed so far, i usually use the water sentinal brand but lately their prices have gone up too much.  Figured i would give water filter tree a shot.  Perfect fit in my samsung rf268abbp.  This filter also has 100 more gallon capacity prior to changing (400 total vs 300 for sentinal).  The water coming from the fridge has no odor or taste and the pressure is good.  This is my new "goto" brand of filters.  This has the square type notch on the filter head (newer samsung has a shark tooth style and won't fit older fridges with the square head).

Update, after 2 months or so the water taste quality had diminished.
