So my wonderful Mommy got a SodaStream for me for Christmas. This thing is AWESOME! I can make soda and carbonated water. So far I like the raspberry essence, the lemon-lime soda and the diet cranberry raspberry. I am having Diet Dr. Pete (Dr. Pepper) but I'm not impressed. I'm still going through the sample pack, so at least I know not to buy that one. Get one! They are great!
