Unusual $12 portable folding wood and charcoal grill

I bought this pretty cool grill for $10 on Amazon, I can use it with wood or charcoal and it folds up into a very small package. It has a folding floor that when folded up makes a pocket food can be added to so you can cook on the grill or below next to the coals.
I have a propane stove at home and bricks I can use to make a rocket stove, but I wanted something light and portable I could take with me that would burn wood I found wherever I was camping. Most barbecue grills are difficult to add wood while pots are on the grill. This stove allows wood to be added on the sides very easily. I think this will make a great portable lightweight low cost camping stove.
