3 piece Airlock

Slow delivery on product and the airlock was smashed upon opening package.
So I can't give a review on the aitlock because I never got to use it.

Great product, great company. Just what I needed and fast delivery.

I bought a few of these after they stopped carrying the glass, one piece airlocks that I prefer. These are effective, and I haven't broken the plastic (even with some rough handling) but the design allows for rapid evaporation of your liquid. I use vodka in my airlocks and am refilling these every 3 or 4 days. That is a major pain to stay on top of, along with being wasteful. The glass one piece airlocks evaporate much more slowly and can be checked every few weeks.

Plastic breaks very easily. Broke the first time I put it in my fermenter.
