My whole family found this very easy to use even all the kids use it my 5 year old nephew uses it all the time the hardest part is figuring out how much carbonation you want and what flavor to use but a very simple machine.
Not at all. It's fairly simple to make and takes less time to fill up a glass of ice and add the soda. You can even customize it to our own flavor. The only downfall is the soda flavors are some what expensive to repurchase.
