Bests & Worsts Reviews from Amazon

I have three ovens in my kitchen … I cook and bake a lot. I really wanted these to work, especially after all of the good reviews. I used these for a few months and recently noticed smoke in one of my ovens while cooking lasagna and then noticed the liner was turning white and was on fire!! Nothing had spilled on the liner - it was clean. I checked the other two ovens and the liners were turning white on the bottom side, also. I would not recommend these unless you want an oven fire. One was placed on the lowest rack and the other two were placed on the bottom of the oven. All three caught on fire, regardless of placement.
