Review (5/5): Wish I had this years ago.
I almost ruined a while marble counter top in my former house from having a curling iron, IN A HEAT PROOF CASE, on the counter for about 15 minutes each day. Over time it turned the marble a dirty gold color. I had to pay to have it professionally redone before we sold the house. So, I was NOT going to have that happen in my new house. As usual, I searched Amazon reviews for products and chose this pad based on that. It works just great! No discoloration. Now I have it under by curling iron, without a heat proof case, on the top of a wooden table. Not a mark. No drying of the wood, either. Wish I had this years ago!
