We had a 21 cu ft refrigeratorwith a  top freezer for almost 20 years.  
we wanted to replace it since while still working we knew it was coming to the end of its useful life.  We have limited space available in which to put a refrigerator.  The GE is narrower but deeper than what we had.  We love the slate color and the bottom freezer..  With all the door storage the inside of the box looks almost empty,  The door storage frees up so much interior space.
