4.8 / 5.06 ReviewsGreat BungThis is a great solid bung that is easy to fit tightly, yet always easy to remove. I'm never going back to the solid rubber bungs! Great price too.October 7, 2013Better than other stoppers.I really prefer these stoppers compared to the non-universal stoppers. The non-universal stoppers fit snugly, but a bit too snugly for my taste. I say that because I have had those stoppers nearly get stuck in the carboy. I never had one get stuck but it is kind of annoying to have to pull a stopper out of a carboy with pliers. You don't have that issue with these.May 16, 2013Good Bung PluggerThe Better Botte solid plug works great and fits the BB to a T. As others have said it is great for cleaning. Also, it is easy to remove and keeps the better bottle clean when sitting unused for awhile. I'll probably buy a spare at this price.May 5, 2013Good for cleaningVery useful for cleaning the carboy. Great price.April 3, 2013NiceI use this in a 2 liter pyrex flask that is list to take a Number 10 stop. This stopper fits very nice and i use it for sloshing the cleaning solution.March 22, 2013Useful for CleaningI bought one of these at a friend's recommendation. It's extremely useful for cleaning your carboy - I add some cleaning solution to the carboy, seal it, and give it a good shake to release any particulates. I can clean better without making such a mess. I also use this to seal a carboy if I'm storing boiled (and cooled) water._x000D__x000D_January 8, 2013
