With a dissolution rate of up to 60%, this soda maker machine provides you with full-bodied bubbles and a cool taste. However, please ensure not to carbonate for more than 5 seconds at a time and use cold water between 4-5C for richer bubbles and a better taste. *Cost-effective and Sustainable: We provide you with 2 1L food-grade PET bottles with caps for convenient storage. This sparkling water and soda maker does not include a CO2 cylinder. With a replaceable cylinder design compatible with mainstream soda brands' 60L CO2 cylinders, one cylinder can make 180 bottles of soda water (330ml per bottle), making it more economical and eco-friendly for repeated use. *Secure Safeguarding: The safety valve automatically opens to release excess gas when the bottle reaches a certain pressure, ensuring automatic depressurization for safety and preventing the bottle from exploding. Thanks to the excellent nozzle design, you won't have to worry about clogging or freezing. It's truly reliable! About the CO2 Cylinder valve thread: North America/Europe is Tr21, Australia is G1/2 and CGA320. *No Electricity Needed: This sparkling water maker kit doesn't require electricity or batteries, enhancing its flexibility and portability.
