Product review (2 stars): NOT For Gas Ovens
What they don't tell you is you can NOT put liner on bottom of oven if you have a GAS oven. You have to put on lower rack..In my case that defeats the idea of a spill pad on the bottom of oven..They should tell you that in the ad..NOT for GAS ovens unless you want to give up your bottom RACK. Especially if you bake a lot of pizzas...
