Went to purchase a small or medium and came home with a large. All of the display models had stainless dampers and the dealer said all the new eggs came with them. I guess the one he sold me must have been old cause it has a black painted one. Oh well will have to talk to him about that. The thermometer he sold me has a diameter that is much to large to fit in the hole in the egg. Don't know if it's a BGE thermometer or not. Should i try to enlarge the hole or find one to fit it.
