Sugar Free Lemonade - SodaStream 4 "LOVE THIS PRODUCT!!!!!" J 15 August 2011 This review is for an older version of this product Even my fussy boys will drink this. We prefer the sugar free version as it is not so sickly sweet. Get through quite a lot of lemonade in our house with 3 boys. With the Sodastream there are not empty plastic bottles going into landfill so we are doing our bit for the environment too.
