I know @Mark has these as I just read his review. How have you found them Mark? I just bought some from Ozfarmer.
Anyone else tried them.
I’ve never done any fermenting before, I went to a workshop yesterday so are keen to try some.
They generally work quite well. I've had a few jars spoil but it's not certain that it was due to the airlock design - I would say they are a good product.How have you found them Mark?
