Product review (5 stars): Attractive, sturdy, and good protection for burners
These are great. I've had them about three months now and they haven't scratched or warped at all. They're shiny and new looking and they're sturdy enough that I can rest a tea pot or a pan on them without problems. I often leave one on and one off, cooking on the "off" side and using the rectangular cover as extra counter space. Sure help keep the burners clean, too. Very happy.
