"Prompt delivery and friendly service."
not fitting!
"I bought it as part as a glass carboy as recommended. The angle is far too great, and the bung just pops out again. To use it I had to push it in so far that I have to use some tools to get it out. Certainly not fit for purpose. (Self-locking angle in engineering is usually 7deg.....)"
Good product
"Great for 1 Gallon demijohns and also fits 2L flagons"
very good
"fast and good quality, I will order more."
Fits perfectly and very sturdy.
"Fits perfectly and very sturdy. Recommended."
Difficult to use!
"The bung I received is also very short - I bought this for my 23L glass carboy and if there is any moisture at all on the neck/bung it pops straight out. A lot of swearing and trying to find a 'sweet spot', eventually it fell in and I had to DIY a makeshift airlock until fermentation was finished and I could fish it out again. Not at all like the picture :-("
Very Useful
"Works amazing for cold proofing wine in the refrigerator seals tight enough."
Would return as it?s a bit shorter
"The bung I received when I ordered this SKU was shorter than the one in the picture but looks to have the identical angle so the same would apply regardless of which they ship. constantly popps out takes a good 5 min of pushing hard and swearing to get it to stay and even then often pops out 10 min later anyway thankfully only have to use when I have 2 Demijohns on the go"
