Well, aside from the internet and porn.http://www.sodastreamusa.com/?gclid=CNqg48m4vaACFUg65wodiAfjSwI'VE GOT ONE, AND IT'S THE BEST THING EVER.The Root Beer tastes like a float from A&W, the Creme Soda tastes different than expected, but leaves a great aftertaste that doesn't interfere with other flavors (like toothpaste and milk D:), and the Muntain Dew tastes awesome. Plus, it saves you money... Why pay $5 for a box of 12 cans of soda when a flavor bottle (that costs $5) makes 33 cans? You may have to spend that money difference on the CO2 tanks, but still... Also, you can only return the CO2 tanks to a Sodastream selller and they can refill it, because it needs a special kind of CO2 or something...
