Query: no exhaust damper

I was unable to keep a constant temp because there is no damper on the lid. I had to use a stick to keep the lid open slightly. Took forever to cook ribs and chicken and they came out slightly dry because of no convection without the damper. Barrel section was dented also. Very cheap design, I would not recommend this item when there is so many better ones for a quarter of the price.
