I had never seen a charcoal/gas grill as I have had another gas grill for so many years. Whoever thought of this idea was genius! There has been so many times I have wanted to charcoal grill something but didn't want to buy another grill just for that. The gas grill is fast and I like that idea 
but sometimes you just want the smokiness in your grilled food so this all in one is just what I wanted.
