Tried a new airlock design from a craft fair and my whole batch went bad

I spent about $15 on this fancy glass airlock that looked cool but didn't seal right. Lost a 3-gallon batch of sauerkraut I'd been working on for a month. Anyone know a reliable brand for basic airlocks that won't fail?

Honestly, that glass airlock probably worked fine. I've used similar ones for years without a single seal issue. The problem is almost always user error, like not setting the lid correctly or having a bad gasket on the fermenter itself. You should check your crock or jar before blaming the airlock.

Ever have that happen with a plastic lid warping? Mine stopped sealing right after a few hot washes. Switched to a metal one and it fixed my airlock problems.
