The second time we used this grate, I heard a loud "pop" and discovered that the grate had cracked on the back side. We continued to use it throughout the season, and it worked just fine.
Of course, Wayfair sent us a new one upon hearing that our's cracked so soon after purchase. Planning to use the new one this year. Hopefully it will hold up better than the last.

Cons: Cracked in the heat after just two uses
