Product review (5 stars): God produt, great tasting water.
So far so good.  The water tastes as good as the factory filter for less than 1/2 the price. The seller is also very proactive and guarantees their product.  They contacted me after the sale and said if I was unsatisfied for ANY reason to let them know.  It is a great product, so I don't plan on taking them up on their offer.  :)
