How much grate area do you need?
Total cooking area usually adds upper racks to the main grate. Compare the main grate for steaks and burgers and the total for low-and-slow batches, and treat serving counts as manufacturer examples.
Which temperatures will you actually use?
The lowest setting matters for smoking and the highest for searing. A direct-flame or sear figure is a separate manufacturer claim from the controller's set-temperature range.
What does the connected controller need?
Record the app, the Wi-Fi band, any Bluetooth step and account requirement, the probes in the box and the clearance, outlet and cord conditions in the manual.
