Big Mouth Bubbler carboys fitted with a valve and dip tube.
Have you had any issues with the lid on these? Seems like everywhere I look, there is someone saying the lid sucks, and someone saying they don't know what the other person is talking about... thinking about getting one and using the glass carboy I have for meads.
The original BMB lid design had seal issues. The new lid design, introduced about a year ago, seals well.
