Stack up two lines of wood or pile up a quantity of charcoal, then start the amazing fire starter "Feuer-Box" and you will enjoy a burning fire within a few seconds. The "Feuer-Box" lights the wood from up to down, causing only a minimum of smoke and carbon monoxide. It creates 50 % less gases in comparision to a standard fire starter. The "Feuer-Box" burns  for 20-30 Minutes. After this time the woodburning stove has already achieved it´s operating temperature and you can go on putting more wood to the fire.
Using the "Feuer-Box" for lighting a charcoal BBQ it is the same way: Fill up charcoal, light the Feuer-Box and put it on the top. You can enjoy a burning fire after a few seconds. When the Feuer-Box has burnt down, your charcoal grill has enough temperature to start cooking.
