Product review (1 stars): BLECH.
The taste of the water that comes out of my fridge is just AWFUL using this filter.  It's actually worse than drinking warm water straight out of the tap.
 Once I installed, I had to dump at least 2 gallons of water before the gray color from the charcoal disappeared.  We fill a few water bottles daily in addition to regular drinking water during meals and had been using this filter for almost 2 weeks before I finally just switched back to my old filter that I had saved in case this one didn't work.  Thank goodness I did!  HUGE difference in flavor.

This one is about 1/5 of the price of the name brand one I got from Sears.  I guess you pay for what you get.  I guess I'm going back to paying $50+ for the real filter.
