Son likes these; but doesn't love them. They're a little small for how much oatmeal/soup he takes with him & while the ceramic works well in the microwave & keeps things warm for a while, it just wasn't what he was looking for. These would be great for smaller kids or people who are portion conscious, but they are a bit on the expensive side. The lids kinda-sorta work, just not in a microwave. I often head first to the Corelle store before going anywhere else. I know these will be used, but just not for what we originally intended. Sorry, I can't be more favorable.
