Product review (1 stars): BEWARE!  RIPOFF!  I suspect you may get a already used up filter.
BEWARE!  RIPOFF!  I installed the filter in Feb 2016 and the water did not flow well at all.  No better than the one I replaced.  I thought maybe the water pressure must be low.  Then I had enough and went to a well known large hardware store and purchased the same filter but it was packed in plastic which in no way allowed tampering.  The one I received from Amazon was in a filter box. To my pleasant surprise the filter from the large hardware store worked great.  I now suspect the filter I received from Amazon was a used filter that someone replaced and sold it to me.  BEWARE!  It did not work.  Save your money -- it's cheaper because it's used up.....  Just to be fair - I have bought other Samsung filters in the past from Amazon and did not have any problems.
