Product review (2 stars): Poor quality and taste of water.
We followed the directions and dispensed the required amount of water after installing before using. (Seem like such a waste, so we used that water to water our plants)  Even after a months use, we still see some bubbling/suds in our glass. The taste is a slighly different that the last time we changed the fliter.  We're not sure if we got a bad one or what, but from now on, I think we're just going to get it from a local trustworthy hardware store instead of ordering it online.
