Product review (1 stars): Set off my fire alarm
I admired some liners my sister had in her oven and bought these for their good reviews. Since I have a gas oven, I cut and placed one liner on the bottom rack. Don't know what I did wrong, but both times I used the (clean) oven with one of these liners, it started smoking and the fire alarm went off. There were scorch marks on the liner from the wire rack and a weird smell. I decided these weren't for me and won't use them again!
