Product review (5 stars): Works fine out of the box with my GE Fridge
Bought this for my GE refrigerator as a replacement for my MWF filter. Was nervous based on some of the reviews on leaks and needing some  kind of special "o-ring" but that wasn't my experience at all. Out of the box this filter worked fine for me. You do need to read the instructions and run SEVERAL glasses of water through the filter before the water will run clear. But I'm not noticing any difference and it was less than half the price of the standard filter. Would buy again.
