Product review (5 stars): Worked great.
The installation of this replacement is slightly different from original and I initially thought it wasn't going to work.  The original had different threading that guided the filter into place more like a true threaded screw where it kind of worked itself up into place.  To get this in place, I had to align it just right, push up and then twist to lock.  Got 3 of these for $43 versus $30 for just one GE original.
