Product review (4 stars): May need to fiddle with it to get it to work
Wrong part - this is not the RPWFE type in the picture on the Amazon website and does not fit my fridge.  It lacks the ID tag to let the fridge reset and operate.  I do not know why GE kept the same part number for both - RPWFE when they are clearly different.  In picture my filter on left - which is the same as pic on Amazon website (note bottom of filter) - filter sent it on right with box.

Revision - I got it to work after all - it does have the chip.  I reinstalled it a couple times and made sure to push it hard against the wall of the fridge so the chip was close to the reader and it worked.  The fact that the bottom shape and water end is so different is disconcerting but it seems OK so far.

Four stars because of high cost - GE's fault, not Cheddy's.  Despite outrageous cost the GE &(^%*& still had to make it in Mexico - got to make sure the CEO gets that 3 mil bonus this month so he can buy a new manion / boat / whatever.
