Product review (5 stars): Love FitFabHome Large Oven Liners
After reading reviews for oven liners, I chose FitFabHome.  I still had a question about using them in a gas oven, so sent the company a message.  Not only did they reply very quickly, but gave me valuable information.  For a gas oven, the liner needs to be placed on the bottom rack, but you don't "lose" the rack since you can place food you are baking or roasting right on the liner.  I sincerely appreciate the timely reply with concise information.  Very happy to have a sparkling clean oven with the easy clean liner to protect the bottom or floor.
