The Maze Sub Ohm BF RDA by Vandy Vape is the first ever sub ohm rebuildable atomizer. The Maze RDA is designed to be used with the Maze Coil which features a 316L SS maze wire with Japanese organic cotton with an resistance of 0.2ohm. The coil is fully replaceable like a sub ohm coil and has a massive surface area like a "stove-top," creating a more flavorful vape and massive vapor production. This RDA can be filled through two methods, first, through a squonk bottle with its squonk-ready pin, or second, through the central filling tube on top. Airflow is directed through the RDA through four sets of 9 small airflow holes that are fully adjustable.
