Product review (5 stars): Took a flyer on this and it worked great. We've got pretty good water to begin with
We bought two when this product was just a few months out from its debut on Amazon.  Took a flyer on this and it worked great.  We've got pretty good water to begin with, so perhaps our use is not truly testing the limits of its efficacy.  However, we did not find any strange or foul tastes/odors with its use and will definitely purchase more -- especially given the cost as compared to OE.
