Will it make my grill easier and quicker to use? I am busy and that's the one complaint I have about charcoal grilling is there's a bit more setup time in getting going.
IMHO ... Maybe Yes, maybe No ...
You must look at what your cooking for your family.
Burgers, steaks, fish, etc. let's call these categories Med-High heat, some cooked directly & some cooked indirectly. Probably not needed regardless of how high a quality accessory it is ... and it is high quality.
Ribs, Pork-loin roasts, brisket, etc. usually called Low heat cooks (need extra time to break down fiber). Possibly useful since it takes less time to fill with coal, to start the startup coals, and far easier to re-fill water pan and/or coal holder.
One side note: The current cost of this accessory is probably less than the cost of a pair of bone-in rib eye roasts. The SnS, along with a good Maverick 732 would cook those roasts to perfection
