The Wolf-Call RDA by Smoke-E Mountain does things a little different. The deck is milled from extremely high grade 316 Stainless and uses an innovative valve controlled air flow system with no visible airholes on the device. This is a 3 post design with the negative posts being milled into the deck for superior conductivity and features PEEK 450 insulation on the positive post. The top cap is threaded and adds to the monolithic presence of this atty. The valve system lets you use various included "plugs" to constrict or even completely disable the airflow at each individual air hole.
