I have used both of
"I have used both of the fermenters I bought 3 times each now, and each time I have had difficulty getting the fermenters to seal properly. They seem to be leaking air slowly as the airlocks stop bubbling quite quickly. Play around with the lid and they get going again but it doesn't last that long. Hope it hasn't affected the beer of which the first batch will be ready in about a week or two. I've been brewing for a lot of years now and haven't seen this before."
