I have the SodaStream and like it except for having to deal with refilling the cartridges. A pain to exchange. I'm also not getting the amount of liters they say I will. I came across a gizmo on Amazon called Twist & Sparkle that has good reviews. It uses those single small disposable cartridges. It doesn't take up that much room and is about $35. What I like is that you can fizz any liquid but milk, unlike the SS which you can only use water in. I don't like that you have to hold the top for about a minute until it finishes fizzing.
Has anyone tried both? What are your thoughts on these? Which do you prefer and why?
