The Sodastream Fizzi and Jet are two different models of home soda makers designed to help you create carbonated beverages right in your own kitchen. While they share some similarities, such as being easy to operate and offering a wide variety of flavor options, there are also some important differences between the two machines. The first thing that sets the Fizzi apart from the Jet is its design and appearance. Whereas the Fizzi is a sleek and modern-looking machine, with an all-black finish, the Jet has a more classic look, with a silver base and clear plastic rather than a metal bottle. Both machines share similar features, such as customizable carbonation levels and simple one-touch controls, but the Fizzi also includes a unique CO2 usage tracker that helps you monitor how much gas you're using and replenish a tank when needed. Overall, if you're looking for a stylish machine to help take your beverage game up a notch, then the Fizzi might be the right choice for you. But if you prefer something a little simpler or have limited space in your kitchen, then the more compact Jet might be better suited to your needs.
