Why does SodaStream recommend to always have more than one cylinder?

We recommend keeping a back up carbonating cylinder handy so that when one cylinder runs out, you simply swap the empty cylinder for a full one. That way, you'll keep enjoying fresh, fizzy drinks without interruption. You can exchange the empty carbonator via courier service, in a store near you, or through our Sparkle Saver's Plan.

Sparkle Pro-tip: Order 2 CO2 exchanges to save on shipping and order 3 or more to get FREE shipping.
