NB had them really cheap a few weeks ago so I picked some up to try. Plus, they don't take up any space so I can fit my carboys in a tighter spot that I have. I decided to try one after about a week of fermenting with a typical airlock. The beer was still bubbling pretty strong. I got it on there and waited a few minutes, not sure what to expect. I didn't hear any burping or anything. I pulled up on the top tab of the seal and heard a woosh and felt the air hit my face. I switched back to my traditional airlock after trying the waterless for a while.
How much pressure is acceptable? Does anyone have any experience fermenting with this style of airlock?
