Product review (5 stars): Perfect
A fraction of the cost of the factory one - no discernible difference in performance or taste of water. Both the hydrogen and the oxygen particles flow through the device without complication, although it seems like twice as much hydrogen as oxygen passes through the filtering media. Also, the water does taste strongly of dihydrogen monoxide, but I like my water to taste like that. Cuts the scotch perfectly. Save money! Viva la cheapskate!
