Robert,
I've got both a stacker for the WSM and a Bandit. The stacker may as well have been made from aluminum foil. Not many redeeming qualities about it. The Bandit, however, is built like a tank and functions beautifully, with the exception of the grease that sometimes runs down the sides. I also appreciate now having a 22 1/2" compact kettle that I can take on the road with me.
