What is the difference between the Quick Connect system and the Screw-in system cylinders?

We made changes to our cylinder system to ensure our consumers get the most comfortable experience. 

The Quick Connect handle system is part of the next generation of cylinders. It 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.
