What is the difference between the SodaStream DUO™ carbonation system and some of the other existing sparkling water devices?

The new Quick Connect pink handle system, which is used in our SodaStream DUO™ Sparkling Water Maker, offers a new and effortless way to insert and remove your gas cylinder without the need to screw it into the Sparkling Water Maker. You no longer need to check if the cylinder has been tightened enough or too much.
