Product review (2 stars): Might want to spend more to get a better filter
These seemed good but didn't last long.  We expected it to last six months or so but they only lasted about 2 months, if that.  One went bad and barely let the water through after a few weeks so that the refrigerator water dispensing was barely squirting water out.  We replaced it with another brand new one from the box and that fixed it but that one didn't last as long.  When they are working, they work well.
