Product review (4 stars): Good Substitute
When our GE Profile side-by-side told us it needed a new filter, I decided to take a chance on this one based on all the positive reviews. My only concern so far is that it was a bit trickier to thread it into the filter holder than the genuine GE MWF filter. It doesn't have the arrow marking that the GE one has to line up with the arrow on the holder. Simply start with one of the flanges facing forward, push firmly up then twist into place. After running 2 gallons through the water dispenser first; the water tastes fine.
