Making carbonated, sparkling drinks with Sodastream at home allows me guilt-free addictive Coka-Cola substitute (almost), anytime. My son-in-law and his wife handed down a SodaStream unit they received on their wedding, bottles and 1 carbonating bottle. I like the fizzy taste of the sodastream drink. We can, also, get the flavors of about ten available ones to choose from. My favorite fizzy drinks are Cola and gingerbeer.
