Product review (1 stars): Not great
They fit my GE fridge and that's about the only good thing to say about them.  Not sure if the fridge has a sensor for the indicator or how that works, but 2 weeks after installing one of these and resetting the system the light went red again. The water also tasted really bad. One person even commented that the water smelled moldy.  It was bad whatever it was.  I've since stopped using the water from the fridge and just got myself an RO system.  Now that's good water
