Solidly built, great heat retention, great finish. This thing is fun to cook on and makes great food! I’m thankful to have the half insert and half regular grill on my Genesis 300. If I need the entire grill, I can pop out the insert and put the grates back down. The shape is odd. It looks like they could have made it another 1-2 inches larger and I would have appreciated that extra space but it’s just big enough for me to make food for 4-5 people. I’m still figuring out where to set the heat on it and I figure that will be a process. So far I love it!
