Product review (1 stars): Gave water a metallic taste and gray tint.
This cartridge made the water have a very metallic taste and gave the water a gray tint.  I flushed gallons of water through the cartridge and even tried to keep using the cartridge for more than a week and the taste did not go away.  I eventually took out the cartridge altogether and am just using the bypass plug.  I'd rather drink unfiltered water than use one of these cartridges.
