I really like this machine! I have two younger children and my daughter wanted to try drinking pop, I really like that this machine allows me to make pop at home and choose how bubbly I like it. It's soo simple to use. We fill the bottle with filtered water and then click it in and push down for the bubbles (my daughter thinks it's the coolest thing to watch) then simply add the flavour syrup that you like. It's wonderful that it doesn't plug into the wall and takes up very little space on the counter. The thing that I like the best about this machine is that I can customize my soda (I figure this out by accident). I made the Diet Cola and added some cranberry raspberry to it and now my husband (who won't drink diet cola) keeps drinking it on me!
