I ordered the product and used it once. It performed well enough with the cooking. I used the mats for cooking hot dogs and hamburgers. Nothing burnt, but the mats looked like crap. I called the company, followed their instructions to clean the items, and it didn't work. Later they contacted me to see if I was satisfied. When I told them of my story and submitted to them the email chain, they told me it was over 60 days, and the warranty expired.
They claimed that I probably cooked the food at over 500 degrees and that was most likely why the mats looked burnt. Absolutely ridiculous! I have no need for this company, and all I wanted was a replacement, not a refund.
Lesson learned. I recommend Kona mats. A better product, a better price, and a better guarantee.
Bottom Line: No, I would not recommend this to a friend
I find it interesting that other people have a similar experience with this product. After posting this review, the people at Copper Chef Grill Mat want to discuss my purchase!
