Works great with my FerMonsters. Make sure you put it in while lid and stopper are both DRY and works great.

Best Stopper on the Planet!
Yup...it's a stopper. Strange I would be asked to review it. It works. All I can ask for.

Is it just me?
It’s a stopper. It’s fine, but these don’t fit quite right in my 6 gallon carboys. They pop out unless I jam them in so far that I need a tool to get them out.

Great stopper
I use this stopper on my Fermonster carboy and it works great!

Fits my carboys and seals out the germs. Airlock fits snug. No problems. Does exactly what it is supposed to do, and what you'd expect it to do.

Perfect fit for Better Bottle
These are a must have for Better Bottles. They can push pretty far down into the mouth of the carboy and become difficult to get out. It would be nice to have a lip around the top of the stopper to prevent it from going too far down and to give you something to grab hold of to pull it out.

Great for 5- and 6-gallon PET plastic carboys!
I use PET plastic carboys, and these stoppers make a great seal. They are easy to clean and sanitize. They are very durable as well. I love these stoppers.

fits good works good

These will easily push right through most carboys and better bottles
These are not the best choice for carboys, they'll push right though. I'm going to try the 10.5 and see how that works. They will do the job, just not sure how I'm going to get them out.
