Product review (2 stars): No better than a brita filter.
I honestly can't tell the difference between the filtered water and what comes from our tap in Boston. I filled two glasses, put them side by side, and and let them come to room temperature. When I do that with a charcoal water stick filter (the kind you stick it in the pitcher for a few hours, I can definitely tell the difference, but this fridge filter seems to be about as good as a brita. Not worth the money, in my opinion. I hope it's taking out some of the lead and other impurities.
