Product review (1 stars): does not work
This water filter doesn't work.  The instructions say that the picture of the lock on the filter has to line up with the lock in the refrigerator but it doesn't .  We tried both filters in the 2-pack and neither lines up.  After using the first filter for only one month the water coming from the filter was brown and foul-tasting (far worse than the tap water).  It seemed like there was a reverse flow of residue.  Don't buy this one.  I've ordered the factory original ($15 more + shipping) and hope that will be better.
