I do not like plain water with meals. I had heard of SodaStream devices and I gave it a shot. Not disappointed for a second. My advice to those who become addicted: buy a second cartridge immediately gas ... it avoids "out of gas". Second stupid little advice for the followers of soda with syrup to the syrup before the water does not exceed the line on the bottle, it will save you an impetuous overflow. Device quickly pays and repaid by the savings made on the purchase of sodas.
