### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Broke one, thank goodness it came with two.
  

*by D***N on Reviewed in the United States on December 6, 2018*

The smaller section of the rubber that you fit into the mouth of the carboy doesn’t have a lip on it, so it makes it pretty hard to get out of the bottle. Broke a few chop sticks getting it out. Does it’s job, a little too well. But all and all, it does that there bubblin’ just fine.

### ⭐ 1.0 out of 5 stars

Don’t like the cylinder shaped one. Fruit flies got in!
