My fiance and I are HUGE fizzy water drinkers, so I got us a SodaStream for Christmas and we LOVE it. Neither of us drink soda, so we'll never buy the syrup, I'm not sure if our sampler pack that came with it will ever be used.

But yes, best invention ever. Now when I'm craving a soda water (which is, uh, all the time) we can just make it at home from our regular ol' tap water!
