Product review (2 stars): Be CAREFUL
We have a brand new gas oven.  I used this liner for the last month or so and have found that when I start the oven the gas odor is so intense. I ended up cutting air slits in the liner but even that did not eliminate the noxious odor.  I ended up throwing this liner away. It could be that it is not made to be used with gas.  Don't bother purchasing!
