Vision Grills, based in Saint, Louis, MO., is a kamado company to keep your eye on. They’re coming on strong with patented, innovative designs that stand out from the ever growing kamado crowd. Foremost is their unique ProZone system, a slide out insert that includes dual damper air intake, ash removal tray and an electric fire starter. In 2016 they introduced an optional Quickchange Gas Insert that slides into the bottom and converts ProZone models into a gas grill for a quick, mid-week meal. For 2018 they plan to add an optional Quickchange Kamado Grill Pellet Insert that turns your kamado into a pellet smoker.
