Product review (1 stars): OK filter- -too expensive.  No alternatives.  BAD on GE!
This works fine.  BUT I hate that I have to buy the GE brand of filter to keep the 'replace' light off.  This light comes on based on time-installed; not based on the filter's condition.  GE charges a lot for these and I don't know of any alternative since they use an embedded chip for ID/function, and the CALENDAR-DRIVEN replacement advisory.  Lots of good refrigerators out there.  For my next one I'll look beyond GE for this clear lack of customer focus.
