Overall, I find the Sodastream Duo as a water bubbler simply in the handling and reliable in bubbling.I can't say that I myself compared to Crystal 2.0 find so revolutionary.But she does what it should and bubbles the water as I want it.So you can still use Crystal 2.0 decide.But if it is really important to enrich water in plastic bottles with carbon dioxide, you will find a good water bubble at the duo at a fair price.
I've got used to the water bubbler in the meantime.However, I am also the only sparkling drinker in the family.Therefore, a cylinder is enough for me and I get along well with two bottles.If at least two people drink sparkling water at your home, I recommend buying the Sodastream Duo with four bottles.
It is best to compare the offers here, the sets are always cheaper at many dealers, so it is worth the price comparison.It is best to think that I really don't have to drag bottles with a water ripler and can always bubble, as much as I want.
