No more fingers burnt from trying to light the burner with matches or those ever faulty spark lighters. Thanks to the Auto ignition in the knob lighting the burner becomes extremely easy and convenient. You can do everything with one hand. Press and turn the knob to light the burner. Take the heat off yourself, and make kitchen work convenient.
It might get dangerous if the burner accidentally goes out. However, not in Hansa gas hobs which are equipped with a special valve that cuts off the gas supply. Safety above all else!
