Product review (3 stars): Great, but then not so great
It was 5 star out of the box because it didn't make the loud noise I was having from cheaper, generic filters. However, after a month the loud noise is back.  The difference is the noise is only occasional and the generic filter was loud every time.  We drink a lot of water so we use our refrigerator very often. So, if you have the loud noise I would recommend switching to this filter, just don't expect it to be perfect.
