Product review (1 stars): Only Delivers One Cup
I was excited to get this as a low-cost replacement for the filters I had, but unfortunately I was only able to get one cup of decent tasting water out of it. Typically when I install a new filter, I run 2 gallons of water through to rinse the filter, and then it takes another day or two till the water is great again. I think this is because of the small cold water tank in the fridge.

With this one, I ran two gallons through, and thought it seemed to be tasting fine. The next day, my wife said it still tasted funny, so I figured it just needed a little more time. Over the next few days, it continued to taste worse and worse, until today I just couldn't take it any more and put in a new filter.

I thought maybe I just got a bad one, but the next filter had exactly the same flavor after the 2 gallon rinse. I can't afford to pay $7/cup for filtered water, so I am using something that delivers multiple good cups.
