My kids and I have so much fun using this! The whole thing is as big as a keurig machine. Comes with the water container to fill, a CO2 canister to make fizzy bubbles for your drinks, instructions with drink ideas inside of it and comes with 8 different flavors you can add in the water.  You can use it just for still water (which I like) or can make it like soda, adding a little fizz or a ton. You can use 1 flavor or 2 flavors at the same time and choose from classic flavor or bold flavor where it's more. Overall i think this is pretty awesome!
