The Vaporesso 0.2 ohm QF Mesh replacement coil head is intended for use with the Vaporesso SKRR sub ohm tank, and provides excellent vapor and flavor production when used between 55-85W, with a mesh heating element helping to maximize the area over which the heat radiates, resulting in more vaporized juice. With a wicking layer composed of 100% organic cotton and flax for optimal flavor and longevity, these replacement atomizer cores are a perfect choice for anyone looking for an excellent mid-wattage option.
