I bought a sodastream, and thought it was a good idea. You only get 60 litres if you use the first light, and it hardly has any bubbles. I wish I had bought the more expensive one for $300. from another company. $40. for a CO2, even with the $16. rebate on the empty one, is rather expensive. I think them saying 60 litres is false advertising. Maybe 40-60 depending on usage would be better.
