I have the Cobb with all the accessories and love it. I keep it packed with matches, charcoal, and fire stater. We are ready to go at a moments notice. I also use it at home on the table on our screened in back porch.
I do everything from baking bread, to roasting wonderful entire chicken meals, and making pizza. Just have to remember to leave the lid on and not peek, so the heat stays in. terry r.
