Product review (4 stars): It's a filter... Never had an issue.
Not much to say here... It's a filter that goes in the fridge to filter our water and ice. It's very easy to install, just open the small door, pull old one out, line up two notches (inlet and outlet), push in and close the door. Very simple to install. Don't forget to run 2 gallons of water before use! It's just to make sure any lose material runs out and isn't ingested.
