Since Christmas, I use a SodaStream machine and I am very satisfied, and uses every day. For cons, I am much less adept flavors offered by the brand. The flavors Coca ... I have not finished the bottle bought ... firstly because despite several trials of different dosages, taste obtained was never very satisfactory, or even simply good! Then because the opened vial has not kept long: the content has become very viscous and difficult mixture in sparkling water. The flavor lemonade became my "favorite" but by default because others tried did not convince me ... And I think the second finished bottle, I do not redeem more. I will do more simple: a perfume "ordinary" of another brand, and cheaper, my business does well!
