Product review (5 stars): Excellent replacement versus OE filters.
Filter is WAY better than I expected.  The fit was perfect in my GE Monogram french door refrigerator.  As far as filtration goes, the water tastes as good as it did with the OEM filter, however there is a major plus with this filter over the stock one.  The water flows about 2.5 more quickly.  Gone are the days of standing at the fridge at 2am waiting for a glass of water to fill for 45 seconds.  It now takes about 15 seconds to fill a glass and I couldn't be happier.  GE filters b'gone!
