I use GrillGrates regularly and contrary to some postings, I feel that they add another dimension to cooking on a gas grill. They even out the heat, prevent flair ups and can be used for a sear or for grillmarks. Easy to clean and they can be moved to a charcoal grill and do a good job on whatever you cook. Amazing Ribs has a review on them as well as ManCave Meals, both are very favorable as to their use and performance. Check out their websites and make your decision. I like mine and use them often. I'm sure other members who also have them will agree with how well they work.
