Saul and I drink a lot of sparkling mineral water. A lot. We tried to scale back because of the environmental impact, but it was all too often that one of us ducked over to the corner store to buy a bottle of Perrier (Gerolsteiner was our drink of choice, but buying it by the case at the grocery store was too committed for us).
So we thought we'd try the Penguin Soda Club, which adds a gentle to hearty dose of CO2 to your tap water. I don't know if the Penguin itself will last forever, and the CO2 cartridges are only good for about 60 liters, but that seems a lot less wasteful than buying 60 liters outright. The water tastes great (three blasts on the tank give you Gerolsteiner equivalency) and I like the glass bottles that come with the Penguin (the regular Soda Club machines give you plastic bottles). I'll report back if we have any problems with the sturdiness of the Penguin.
