I dnot think so. I have owned a Sodastream for over three years and use it weekly. I even use Coca-Cola syrup that I buy from Sam's. Fresh Soda is the best Soda. Own both sotcks to and up 18% on Soda and 15% on KO. Hope the KO split doesn't slow down KO but I afraid that Soda will eventually.
has anybody every looked at Sodastream from a infectious control aspect. I for one find it hard to visulize the avarage person sterilizing there plastic bottles for reuse. To simple rinse out for multiple uses leaves me kinda cold. I'm sure Sodastream probably addresses that in there instruction sheet, however, people tend to bypass that aspect over time.
