Related to my sibling comment, I donated my Sodastream to my girlfriend and have tried repeatedly to get https://www.amazon.com/Machine-Cylinder-Adapter-Canister-Sta... to work with a tank of CO2 from the local brew store, but it always only fills the bottle up about 50% which is a huge pain

My current theory is to try and involve a vacuum pump to create a vacuum in the bottle to force more CO2 in but I'm waiting on vacuum oil for my pump to try that out

Anyway, if anyone has positive experiences loading sodastream bottles locally using a CO2 tank, I'd welcome that experience

I'm aware there are hoses that run directly from the CO2 tank into the sodastream but I am not yet on board with its failure cases
