Had this unit for 6 months now. All 3 burners light every time and no need to worry about batteries anymore as I had these issues with a previous bbq. Love that they stand behind their product for so many years warranty. Hoping to add a few accessories in the near future like the rotisserie. Only thing I wish was different would be that the bottom cabin would be fully closed in at the back so I don’t find my dog licking out the grease drip pan. 
I do recommend this grill!
