Burners work fantastic, I love having 5 burners with the center burner being at 18000 BTU water boils pretty quickly.  I purchase the optional griddle that fits just perfect where both burners have the exact BTU to heat evenly.  The LED lights let me know which burner are on with just a glance.  Only flaw is the stainless steel scratches easily when I wipe dry with soft absorbent paper towels.
