my favorite airlock
The size of the "mouth" is good for various sizes of bottles. I am using it for the 96 fl oz bottle of apple juice, it also works on the smaller bottles of juice. Its easy to use and durable too! So far it's my favorite airlock.

Successful airlock
I have made wine successfully with these. Fits most juice bottles. Only had one jug of juice it didn't fit.

Nice Airlock
I've read a three piece airlock is the best type and I agree. You would think less moving parts would be better but I don't think so. This airlock seems cleaner and more efficient. I just today started using mine and time will tell.

They work!
Absolutely needed for home wine making. Keeping air out but allowing the fermentation gas to escape is essential to good wine making.

Afforadable and Effective
I purchased one set of these, and they work so well, I purchased another set very soon after. Thanks to a review by another customer, I modified plastic mason jar lids to fit these (made holes with a Dremel and smoothed and refined them by hand with sand paper), and they are working great! Yes, they are inexpensive, but they don't feel cheap, and I expect I will be using them for a long time to come. It's cold where I live, so fermenting sauerkraut, pickles and sriracha can take quite a long time; with these installed on my lids, I haven't had to worry at all about mold forming or manually letting the gasses escape. A small price to pay for peace of mind!

Wrong details information.
On the order details say 3 items, but I received only two. Not happy with this.

Worked perfectly for fermenting my ginger mead
Used this airlock for a batch of ginger mead and it did exactly what it was supposed to. Fit securely on the bottle and handled the fermentation process without any issues. Simple, effective, and just what I needed for a clean ferment.
