Too bad, in principle it is also clear that water from a glass carafe much better taste than from a plastic bottle. A pity, however, that the technology is not mature. I wanted to give this instrument my mother (81), as a replacement for the old soda bubbler. But the opening of the thread is associated with as much force that even I need this much power (46), for my mother, it was even after several attempts with both hands impossible to turn the screw to open the container again ... I very much hope that as SodaStream will improve in subsequent models even some ... We had to return again.
