It takes less than 5 seconds to make soda! And the best part is that I don't need to plug this into the wall outlet. No batteries are needed. You can make soda anywhere. This is really convenient. I use filtered tap water, and 5 seconds later, the filtered tap water is carbonated. I just add in the flavoring that I want after the water has been carbonated. I tried adding lemon juice, pineapple juice, and cucumber juice. To make it even healthier, I used liquid stevia as a sweetener.
