Product review (5 stars): Got to use it if u want good tasting water
I got city water an u know city water, it takes out the bad taste of the water, the chemicals u see when u get a drink at the sink.  I think it ought to last longer than 200 galleons of water, but at the price its charged at, at the store is high way robbery at its best.  Lucky that Amazon sells it for a lower price, other wise people never would use it after the free one that comes with it.
