perfect for home winemaking
These specialized stoppers (with a hole for an air-valve) work equally well whether you are using 3-gallon glass jugs, or simple spring water "milk jug" like plastic gallon jugs from the grocery store. They fit either application perfectly. They are conveniently sold in sets of 3 just like the airlocks (which I HIGHLY recommend to go with them- so much cleaner than the balloon-over-the-top method which left me with syrup and fruit going up into the balloon and all over my counter!). These were amazingly effective when used together with "3 Piece Plastic Airlock (Sold in sets of 3)", and together, they did not coast much more than the baggie of balloons that they were replacing! I give them my HIGHEST recommendation for any home-brew or home wine-maker who would like a cleaner method of sealing their vessels to keep the sticky stuff and CO2 in and the oxygen out. (P.S. I can't get the product link to work for the airlock, but you should see it under the "buy together" option for this product. You definitely need them both together, not just one or the other.)

Best glass Carboy stopper I have found
These are the best glass Carboy stoppers I have found. Wash, sanitize, and allow to dry before installing in your Carboy then install the Airlock. I use Starsan. They stay in place, I will be replacing all my stoppers with these.

Work fine if you boil them
These are not the typical rubber stoppers that I am used to - they are made of a more plastic-like material. As one of the negative reviewers states, these are not nearly as elastic as the typical rubber stoppers. I suspect that they worked perfectly for the user who uploaded the photo with his 1-gallon plastic jugs because the plastic-like stopper was able to put enough pressure on the plastic mouth of the jug and stretch it ever so slightly to create tension. On a similar glass jug this won't happen since the glass won't budge, and your stopper will end up pushing itself out much of the time. But there's a fix! Just boil these for a short amount of time and they become very malleable. Take the boiled stopper (using a towel or something) and push it into the glass carboy, and it will mold to the shape and create an effective seal. Yeah it's an extra step that you wouldn't need if you were using a more traditional rubber drilled stopper, but it works fine.

Fits a growler!
Made my own CO2 system for my fish tank. Standard fish tubing is too small. You will need to buy some 3/8" tubing to fit in the hole. If you are building a CO2 system, here is how I did it: Fill growler with a 1/2 quart of warm water, 1.5 cups of sugar, and one packet of yeast. Cap on, shake well. Stopper in, carefully pound into bottle, then add 3/8" hose. Hose should be a few inches above the water. Route the tube into the aquarium and after a while, you will see the water start to escape the tube. That is the build up of CO2 working through the tube. By the next day you should have CO2 bubbles every few seconds or so. This system has worked well for over a week now. I plan on changing the bottle every two weeks or when the CO2 stops bubbling.

Has holes in it. I didnโt expect the airlock holes to be there. I didnโt read.
Has holes in it. I didnโt expect the airlock holes to be there. I guess I didnโt read or didnโt understand what airlock meant. I meant airtight or locking out the air so somehow, my logic did not realize that these plugs had holes at the top. They are still useful just not what I was wanting. Iโm just trying to plug my carboys, they are filled already

Good bung stoppers
I bought these bung stoppers for making my wines, and they fit perfectly in the tops of regular store-bought juices and milk jugs. These will not fit in 3- or 5-gallon carboys, but that's another purchase for later. They don't seem to deform from prolonged pressure of being jammed into a bottle top.

Too slippery to stay in place in 6.5 gallon glass carboy.
Maybe these might be better for smaller carboys, but unfortunately for the 6.5 gallon carboys I have they refuse to stay in place and get pushed out. There is just not enough friction to keep them in place.

Well made

No complaints
Bought this for my brother, and he hasn't complained, and believe me, I'd hear about it if there was a problem! So I'm guessing it works well.

Fail
Not happy about these, they aren't stoppers, they have a hole in the middle so they can't hold any liquid. The holes were not shown or made clear in the pictures or description, this was a big fail for me.
