I've had these before and I love them.  I use my auto clean to clean my ovens, insert the liners, and I know I'm good for another 3 months.  they're easy to wash off, easy to install, and they do what they're designed to do.  If you need to trim one or both, that's easy too.  My upper oven is a little smaller than the lower oven and these fit both.
