nice machine because by electrical connection and takes up little space in the kitchen. easy to use. practice. ecolo: avoids plastic bottles to recycle! and avoids the transport of all these bottles on the 2nd floor at home! well for my teenagers who descend on liter liter. downside: price to calculate cf the gas cartridge. the bottles are one liter and can not be washed in hot water if not in the dishwasher! syrups to be added are too sweet! I prefer the capsules with a preference for the mojito! or I add lemon juice.
