Title: Crud buildup
Review: The lid on this thermos is poorly designed: food gets stuck in the groove and unless you scrape it out by jamming a knife and paper towel in the groove, the crud will stay there and generate mold. Also, the lid often does not secure well, as the threads to screw it are not tight enough.
