The previous one was old and rusted on the cook-top.
It required a lot of wood to keep it hot-which means a lot of time collecting it.
It also was not vented properly which mean a lot of inhaled smoke most of the time.
Now, it is pretty and new and safe. It uses only a little amount of wood due to the coals inside that heat up and hold the the heat for cooking. These are not like charcoal, it is a stone of sorts. They do not need to be replaced for years. And it is well vented so all the smoke goes up and out!
