Product review (5 stars): Excellent!
This product was exactly what was described, and exactly what we needed to help keep our oven clean! It fit our electric oven exactly without any cutting. Since I expect this to last a very long time, I gave one of them to my sister-in-law and she reports that she is VERY happy with hers too! We have an electric range with an exposed element on the bottom and installed the oven liner under the element as directed. It cleans easily, and has survived normal oven temperatures up to 475 deg. F. We do not use the "Clean" feature on our oven, but if we did we would probably have to remove this liner since the clean cycle is hotter than the 500 deg. F. limit for this product. I suspect the oven liner is good up to about 550 deg. F., but I'm not going to try to find its limit!

This was a happy purchase for us!
