Cheap and serviceable
I needed a cheap air locks for some home brewing. These fit the bill perfectly. The rubber bungs fit my demijohns and fermentation bucket's well. They don't handle the very vigorous end of the spectrum as well as the normal ferment end. I've had to rinse and refill when used for a beer fermentation bucket. But nonetheless good value and get the job done.

Nice airlocks. They are tricky to clean round the bends inside however if something like red wine bubbles into them. Fit the standard demijohns.

Good blippers
I recently started doing cider after getting extra garden with apple trees. My old wine making stuff was ok but these are a far better update version and work very well.

Good value
They do the job well and for the price you can't go wrong. I would prefer glass ones because they would be easier to clean, but for the price you can't go wrong.

They work great as an airlock.
I use airlocks for home brewing. I recently got into making wine and these work great. Mine came with a yellow top and apposed to the red top in the product photo, but it doesn't seem to affecting the performance. I have only just started using these, so only time will tell, but I will most likely order from the same seller again.

Very helpful supplier
Evri lost the original shipment. The supplier shipped next day via RM. Thank you. The airlocks are easy to use. Not so easy to clean so are replacements.
