Product review (4 stars): Lose the Foil
These are a great option if you like to protect your stove with foil wrap. We always used foil to protect our stoves from grease or food stains. Even when I got my own house, I wanted to protect my stove top with foil. But it looked terrible. Foil does not look great on a black appliance range. But this was a good replacement. All I had to do was trim the protective sheet to fit my gas range. It fits great. Measure before trimming to make sure you don't cut too big. Keep a mental note though, these feel like a thick piece of paper. They are not thick plastic or anything. So don't be disappointed when you see a thin package when you get this. They do the job and claim to be dishwasher safe. I haven't had to the need to wash these as yet so I can't say it works. Will have to try to know for sure.

UPDATE:
These are dishwasher safe! I love it. Makes cleaning easier because I don't have to scrap things off my stove while damaging it. I love these protectors. I cook a lot and mine haven't burned. It really depends on how close you cut them to your range.
