Product review (5 stars): GE Product..Be CAREFUL!
These are great!  We have a very hard water, and change filters often.  We have a GE Refrigerator, Side-By-Side.  DO NOT EVER buy a GE anything!!  We bought our GE frig in 2011 and it has never worked properly!!  Have had Appliance folks out here!!  One per year!!  I have a black Samsung frig in the garage!!  It will work circles around the GE!!  Take my word on it.  Spend a little more, or a lot more and get the Samsung!
