The sheet fits perfectly on my gas range stove top. It covers the burner stand and forms like a raised boundry around the stand. It prevents spreading of liquid spills during cooking. I have been using this for past 1 week. It doesn't burn or produce any odor when used; fits perfectly around the burner without requiring any cuts. Easy to wash grease stains. I did not use it in dishwasher though as it was pretty easy to hand wash. I would highly recommend this product.
