Make refreshing sparkling water and sodas and flavoured water in seconds! The SodaStream is so slim and does not require an outlet. Just a carbonator is needed and those are available at most retailers. The SodaStream sparkling waters are a great option for mixes as they are not soda with sugars. You make naturally flavored water without the caffeine. It comes with the water maker unit, 1 Liter BPA-free Reusable Carbonating Bottle, and 60L CO2 Carbonator. I have had it for about three weeks now and can't be happier! It's so easy. I love using it when I come back after work as I'm cooking dinner. That's usually when I have beverage cravings and it seems to give me extra energy through the carbonation. I would recommend this for people who want to drink 8 glasses of water per day to lead a healthy lifestyle, yet find glass after glass of flat water tiring. It would also be great for students or anyone in small living spaces.
