“It works okay at lightly fizzing water. We wanted to carbonate other drinks besides water but they always explode and overflow foam into the carbonator and by the time you can pour, there isn’t any carbonation left. I tried all tips in the manual and even advice from YouTubers with the machine and the only time it works okay is if you only use a tiny amount of liquid (about a third way to the fill line). So it basically just became another soda stream with a weaker fizz but at least we have a stainless steel bottle.”
