If you're looking for an alternative for getting another grill to cook on a flat cast iron surface, this is it. The insert fits perfectly, and is built to provide years of quality results. At the time of writing this review, I've had mine for about a month now, and I love using it. Between smash burgers, cheese steak sandwiches, stir fry's, and everything else, it's brought a new purpose to my good old gas grill. Definitely worth the investment in my opinion.
