but mine fits like a glove
May 14, 2018
I have the Silicone lid for the Joule and it works perfectly. Several people have mentioned that the hole does not fit correctly, but mine fits like a glove. I always clip it all the way down, so the Joule sits as low as possible in the container. There is never a problem. The lid is flexible, making it easy to lift back for adding or removing items from the water bath. Because it is flexible, you do need to go across it like a zip lock to make sure the seal is good all the way.
Before, I used ping pong balls (thanks seriouseats.com). They worked like a charm, but for $12, these are a lot more convenient. Also, they do an ever better job of limiting evaporation. I never have to top off the water.
This thing works great on my 18 qt rubbermaid container, but sometimes that container is just too big, so I bought a smaller one. Stupid me, I bought the 8 quart, which this does not fit. That being said, it works fine. It just does not seal all the way. Keep that in mind. You can use it with smaller square or rectangular containers.
