Better-bottle dry air-locks

Hi all
I was wondering if anyone has ever tried better bottle,s dry air locks? All my carboys are betterbottles and i,ve been just wondering about em…Thanks Tank

Never tried it and at $15 each, I never would. I can buy 12 three piece airlocks (my airlock of choice) for the cost of one of those.

I’ve never even heard of them but I would have to agree with those comments
