Big Mouth Bubbler® Universal Lid - Single Port
The Big Mouth Bubbler® Universal Lid is just like a traditional carboy bung, only bigger! Just as easy to sanitize and set in place too. Ribbed silicone rings ensure a positive seal to keep out pests, while the non-threaded design allows the lid to move preventing an out-of-control fermentation from dangerously pressurizing your fermentor.
Better yet, the port is perfectly sized for all your standard homebrew tools, from a universal carboy bung and standard blowoff hose to a testing thief and auto-siphon.
Easy to clean, just pop it in the top rack of your dishwasher and run it through a standard cycle. You can also use your standard homebrew cleaners and sanitizers.

Doesn't work well with the little big mouth bubbler. Waste of money, stick with the screw on lids even if they are a PITA to open.
Huge improvement over the original lids.

As others have mentioned, these lids have a very hard time staying sealed. They say to make sure the lid and the mouth of the fermented are dry but it makes no difference. After 2 hours, the lid entirely pops off and all CO2 is escaping out the sides instead of through the airlock.
I can only hope my fermentation is not contaminated by this. Super dumb design and the fact that this problem has existed for so long with no resolution or fix is a shame. Avoid this lid and avoid the big mouth bubblers, since as awesome as they are, you've got no choice but to use this lid.
