These are thinner than I expected. They are also much larger than my burners so it took a bit of trimming to make them fit and they don't look as neat (I never could cut a straight line). They do feel like they would clean up easily and are supposed to be dishwasher safe--so no more scrubbing burned on food off my stove. I think I was just expecting something more similar to the old fashioned metal things you used to buy to put under your burners? At any rate, I think these will do what they advertise and will cut down on clean-up.
