Only have it about a month, so far so good. It did have an odor the first few times I used it, but after wiping it off after each use with a wet sponge  the odor is gone. Cleans very easily, keeps oven clean. Don't forget to trim to fit your oven, and put it on the bottom rack, not the bottom of the oven!
