I got this as a gift from my sister. I had a BBQ with some guests. I tried it out for the first time. I placed the mat on the grill and right away the grill showed through slightly (like a shadow). I looked closer and saw that the "copper" was peeling away. It easily scrapped when I poked at it. I decided against cooking on it, worried about the food being exposed to the shredding mat!
I threw it away. Terrible experience. I would never try any other "Copper Chef" products. "As seen on TV" is all it should be!
Bottom Line: No, I would not recommend this to a friend
