i'm not sure if you are talking about the soda stream or not. but if so, my husband bought me one for christmas and i love it. i saw it being advertised on an infomercial, and thought it would be cool to try. it's great in so many ways. it has way less calories than an average soda. your average soda will have about 150 calories, and a glass of sodastream soda has about 35 calories. also it's way healthier because it doesn't have all of that high fructose corn syrup. it's so easy to make and it actually tastes great. some flavors taste more like the real thing than others. so far i think the cola, the dr. pepper, orange soda, and the root beer are great. i am a coke-a-holic and i wanted a way to be able to still drink them but lose some of the calories and this is the way to do it. i hate diet sodas and they are terrible for you. this is the way to go!!
