All the burners work very well and a definite upgrade from my old Whirlpool.  I really like the flexibility of the dual ovens and the across the top grated top (I purchased the center grate to go along with the griddle).  The alarm alert however is extremely weak so have to use an alternative timing alarm.  Like most domestic ovens the accuracy of the oven temperature is not the best so you will need use a cheap oven thermometer if you need critical baking temps.  The ovens themselves do heat up quite quickly.  Over all I would give it 4 1/2 stars
