Product review (4 stars): GE MWF Replacement Water filter by Water Sentinel
Hard to put on compared to manufacturer's replacemnt.  Make sure you  give it  an extra twist so water does not squirt into your refrigerator.  Also make sure adapter comes off old filter to be reinstalled on this one.  Lock it into fitting and refrigerator receiver tightly.
Great price compared to Best Buy for GE product.  Water tastes great.
