Product review (5 stars): These are wonderful and have saved me from many a burned arm
These are the best thing since oven liners--the black oven liners are fantastic and save me a ton of work!  Yes the shelf protectors get dirty and are not great looking after a short time, however when it comes to burning my arms they protect me better than any hot pad or anything else EVER.
I was always burning myself and now that's a thing of the past.  I wish I had found these years earlier.  Now that I am getting older I can see scars on my arms from my baking mishaps.
These protectors are GREAT!
