This is more stable than the pot support for larger pots and pans. Also if you want to use your fire base for keeping warm (i.e. where open campfires are not allowed) you will be able to build a much larger fire and have to add fuel less often. I was able to build a vertical fire with flames kicking up to three feet high, which put out quite a bit of heat. Very usefull for cold weather camping.
