test program at Consumer Reports. In our lab tests, gas grill
models like the 720-0733A (Costco) are rated on multiple criteria, such as those listed below.
Evaluates the temperature and evenness over the grill's surface after a 10 minute preheat using thermocouples. It also gives an indication how quickly the grill reaches its maximium temperature.
High temp evenness:
Evenness of heating over the grill's surface at the highest setting, using thermocouples.
Low temp evenness:
Evenness of heating over the grill's surface at the lowest setting, using thermocouples

Stainless-steel grates Primary cooking grates made of stainless-steel are generally sturdier than those made of coated steel and resist rust even without a porcelain coating.
Coated-cast-iron grates The grill's primary cooking grates may be made of porcelain coated cast-iron, which generally sears meats better and keeps grilling temperatures more consistent than grates made of porcelain coated steel. The porcelain coating usually makes such grates easier to clean than other surfaces, and the grates should resist rust as long as their porcelain coating isn't chipped.
All or mostly stainless Includes more than just a panel or other trim. Based on our limited tests, nonmagnetic stainless is less likely to corrode.
All or mostly stainless
Long-warranty burners While burners remain the grill's most-replaced part, most are warranted for only 3 to 5 years. Better burners are covered for 10 years or more.
Side burner A side burner, which resembles a gas-stove burner and has its own heat control, is handy if you want to cook vegetables or sauce without leaving the grill. A side burner could also be an infrared burner used for searing.
Infrared burner Gas burner that uses infrared technology (ceramic burner, plates and screens, or troughs as some examples) for cooking. An indirect flame is used for cooking food. Burner can be located as the main burner, side burner, rotisserie burner, or any combination of burners.
I cook mostly burgers and hotdogs, some steak during the summer. I was originally attracted to this grill by the nice looking steel construction, and the heavy steel grills. However, I found within the 1st year of owning it that the heat doesn't cook evenly throughout the cooking surface, so the 490 sq in of cooking area can be reduced by at least 25-30%. The worst aspect is that the BBQ caught fire at least 5 times already, ruining at least $70 worth of meat collectively thus far. I think it might be the design of the bottom, as the grade towards the grease cup isn't very steep, so not much gravitates towards the cup. The depth below the burners doesn't appear as deep as other grills, which is my guess why it has caught fire so many times. I had an old Broil king BBQ for 14 yrs and never had it catch fire from the bottom of the BBQ like the KitchenAid did... well I bought it from Costco, so it's going back..
