Product review (5 stars): Filter Works, but Water Line.....
This filter fits perfectly, does not leak, and lasted the full 6 months.  BUT, if you have the new Water Line with an emergency shutoff in the event of a sudden leak, you will need to shut off the water first. Otherwise, the shutoff valve will interpret the filter change as a leak and shut off the water.  Giving you the impression the filter does not work. If you don't want to move your fridge every 6 months, you could replace the Water Line with a standard hose, but you lose the "insurance" of the emergency shut off. Plus, after 6 months I tend to forget why the water won't run when I changed the filter, and you have to remove & reattach the Water Line to release the auto shutoff valve.  Food for thought.
