It works ok but it doesn't stay in the carboy very well

Work great!

Worked just like it said, really helped me control my temps! The stopper holds both the airlock and the tube in two separate holes - fit as tight as is needed, in my view!

Does not work universally.

It works for my big mouth bubbler but slips out of my glass carboys. In the glass I have to secure it down so it doesn't slip out. In the big mouth bubbler it works great and my temp control unit was able to do its job. It cleans easily and the silicon seems durable.

Had a little issue with Gas leaking, didnt hold CO2 back that well during ferment.
But, it is what it is.
