Griddle fit perfectly. I ordered the size for my XL Big Green Egg and it just dropped right in.Super thick, solid steel and really robust build. Edges were clean and no roughness to them. The middle grill part of the griddle fit perfectly, tight but easy to put in, so top-notch build quality.Also, this thing was half the price of competing models. It was even less than a local fabricator said he would charge for a round steel of the same thickness with the edges smoothed and an insert in the middle, so really happy with it.I seasoned with crisbe cast iron seasoning puck and worked perfect. Food slides right off.
