I used mine and it worked great but it does take some time. I would say about 5-10min for 1L so it’s not too practical for a large batch.
The challenging part is after you carbonate it, you slowly have to release the C02 so it doesn’t explode like a pop bottle after you shake it up.
Also, you can kinda control the amount of carbonation in the bottle but if you do it like you would for a soda, it comes out PRETTY damn carbonated.
Thought I would give a report
