Product review (5 stars): GE MWF Refrigerator Filter
The GE MWF Refrigerator water filter was a snap to install.  I was afraid that that water would be all over the refrigerator but the old unit came out with no spills and the new unit was installed with no problems.  Very excellent instructions.  Highly recommended. Only caution is to make sure the new unit is filled with water before installing.  A little tricky filling but easily done at the sink.
