Product review (4 stars): Works great after running a few glasses of water after installing
I got these to replace the more expense filters I'd previously used for my LG refrigerator.  They work absolutely fine and have done so for the past few months that I used them.  I am grateful I read the reviews, however, as the water at first is tinted black.  It clears after running through several glasses of water.  This was not an issue with the previous expensive units I'd purchased, which is why I gave it 4 stars.  However, the money saved are worth running a few glasses of water :)
