I broke down and bought myself a SodaStream. I really don't like drinking water, but have come to like sparkling water. A friend of mine has one and raves about how much she loves it and uses it all the time. I must say, I'm hooked. I have started drinking more water than I normally do and it's just plain fun to make it!
If you're on the fence, I say go for it! I haven't tried the drink mixes that come with it because they are packed full of sugar. I have definitely found a new gadget I love, and I'm looking forward to trying some flavor conditions of my own with it!
(Also, I got the “Jet” and found the best price through Target with free shipping and 5% off with my redcard.)
