We have at our place a 1a water quality. What could be better than to bubble itself. The Crystal is chic and functional. Glass carafes the water tastes better subjectively. But first we had a Monday device. Here was always next to a lot of water while bubbling. The conversion of Amazon was uncomplicated and the new device will work properly now. Specifying 60L on the CO2 cartridge depends on the bubble content of the water. The maximum amount you will likely get only if you generated almost still water. We are satisfied.
