A friend who advised me and so I've started. My husband and I were pleasantly surprised at the sodastream. Although at first this (this model) seems fragile and did a little gadget but within seconds we are left with a liter of unsalted soda water or soda.
It's really a device to have in either and is more economical than buying soft drinks. On average the CO2 cylinder is about 45 bottles of 1 liter and as regards concentrates we use 3/4 of the plug, as a plug gives a too sweetened beverage.
