I don’t particularly use it a ton, but it’s great for recarbonating sodas, or making sodas, or making fizzy alcoholic drinks without having to water them down with carbonated water since you can just carbonate the whole thing. It is essentially just a button to open the hose attached to the co2 tube. Cleaning the bottle topper nozzle thing isn’t bad. Sometimes you’ve gotta wait a while if you overfizz like pure juice (I find it’s better to add some water to help reduce that but if you want it to be full strength juice it’ll just take a while for fizz to go down so you can open the top without it going pop.)

Only downside I’ve run into is the glue on the small bottle I got (got large and small) came off probably cuz someone put it in the washing machine which they shouldn’t have. Still that’s just glue you can fix that, and even then it’s just cuz the bottle is round in the bottom so they glue something so it can stand when not in the machine.
