    Great lid but, has a draw back

    The product is great however, the fermentation can cause enough pressure to raise the lid off. I would highly suggest a clamp ability to maintain a tight seal.


    much easier to use than the regular screw on cap

    For the love of God, please make a lid that works

    I have several of these, and they never seal. Ever. Wet or dry, the pressure always pushes them up. Back when bubblers first came on the market, they had a decent lid that screwed on. Whats wrongs with going back to that? You really shouldn't have to use things like tape or weights to get it to work. This isn't hard, just make something that works easily, every time.

    does not seal

    does not stay down. does not seal.
    I see why people were using straps to hold the lid down.
    Is anyone having success with this lid? I would like to know how.

    Big Mouth Bubbler® Universal Single Port Lid

    The lid is great. You just have to set weights on it for the first time you use it, so that it stays completely down on the mouth. Otherwise, it will pop up on you. One pet peeve that I have was that the EVO 2 Big Mouth Bubbler no longer comes with this lid. Instead the vessel comes with the cheap screw on lid that doesn't seal as well as the Universal lid. You will probably have to buy this separate.
