This inner container means you can leave your crock pot warmer at work and just bring in your inner container to carry your soup. This also works with any leftovers you have or any fully cooked food you would like. This can save you some serious money rather than buying lunch every day that you want a hot lunch.

You can buy extra inner containers as well, so you don’t have to fuss if you forgot to wash it the night before. This is the only way to get more of the inner lid. This part has been noted to fail, so this might become a headache over time. Another thing to note is the short cord. If you don’t have a plug right on your desk, you may need to use it on the floor.
