I'm comparing Sodastream Duo and E-Duo, and I can't figure out (even with a lengthy search) what the difference is, other than price. What could be the advantage of buying E-Duo instead of just Duo?
The E-Duo delivers the gas bursts at the touch of a button. There are 3 different settings with little, medium and strong carbonation. With the Duo, you have to press the button yourself to add as much carbon dioxide as you want.
