A few weeks back I discussed smoking on my Big Green Egg and using indirect heat: I was able to accomplish this by using the Plate Setter. For indirect cooking you remove the grate, insert the plate setter with a drip pan and put the grate on top.
Or you can flip it the other way and use it as a baking stone for bread or pizza.
It’s made a big difference in the smoking I’ve done. Well worth the additional investment. Since I’ve only used it for indirect cooking the bottom is now charcoal black: not sure what effect that will have when I eventually get around to baking.
