The air locks are perfect for what we needed

But, I’m using the air locks with #6 drilled stoppers and they work fine.

Air locks are good but the bung or stopper falls apart

The air locks are fine, but the bungs are too wide at the bottom to fit in a standard 1 gal carboy or the 1/2 gal cider jars from the store.

Air locks are fine but buyers please note that the plastic universal bungs are too large for one gallon carboys and you will need to obtain size 6 bungs to replace ones supplied with air locks

the air locks are fine but the bung isnt even close to fitting my 6 gallon carboy mine is plastic but never the less it says fits all secondary fermenters

These air locks work well and have had no issues

These air locks work really well for fermentation buckets, gallon jugs or carboys for beer and/or wine

Air locks are nice though.

Air locks are never easy to clean which is why I throw them away once bottling day comes

But again, they work fine as air locks

Don’t waste your money and effort in this piece of junk as it will not stay in your bottle top!

it works as it should.

Works as you expect

Work exactly as I’d hoped.
