Product review (4 stars): A bit expensive, but it works effectively
Fits and works perfectly in my GE Profile Refrigerator, Model PSS26MSWC SS.  Only reason for the 4 star is that I feel GE's price point is about $15 too high for this simple device.  Also don't like the fact that the refrigerator's electronics turn on the red "Filter" lamp, every year, regardless of the actual condition of the filter, on the anniversary date of when I first installed the 'frig and powered it up.  Not the filter's fault, of course....
