The ExGo II coil head features a dual-quartz coil design with two coils and two quartz rods, making it able to handle more wax and get better flavor. However, the coil heads do not work as well with variable volt batteries because the resistance is split between the two coils and, therefore, lower than what is required for most variable volt batteries.
ExGo II coils are compatible with the ExGo II and Original ExGo I. ExGo I coils are only compatible with the Original ExGo.
The Apex Mouthpiece is a multipurpose mouthpiece that fits other portable dry herb vaporizer devices such as the Titan I, Kpen, and Gpro. The mouthpiece comes with a screwable metal filter screen to prevent dry herbs from going through the mouthpiece.
