Sodastream is a money making scheme. Canisters are super expensive.
After years of paying $30 per exchange, I decided to switch to an Spärkel Carbonator machine, which just takes a tablespoon of citric acid powder ($5/lb) and a tablespoon of baking soda ($1/lb) per bottle. So much cheaper.
What is the purpose of the carbonator machine? I recall making sparkling water as a kid by mixing the right amount of sodium bicarbonate and tartaric acid (very similar to citric acid) and no hardware was needed: one just had to put them in water, shake until they went into solution and drink.
How long have you had your Sparkel machine and used generics?
I'm very tempted to order the system and use it in a 220V country with a stepdown transformer. The specs on the website say that it's 110V only — I assume that's true for the actual product?
