The Kraken is a rebuildable atomiser (RBA) in the Genesis style. Liquid is stored in the 2ml pyrex tank in the lower half of the device and is drawn up to the coil in the top half via a wick that runs between them. A coil is vertically wrapped around this wick the wick, typically stainless steel mesh, and secured by the screw posts. With three screw posts, there is ample room to run single, dual or even quad coils. In RBAs, you wind your own coils to your own preference.The top half is held firmly in place by o-ring seals; the bottom half can be disassembled by unscrewing to clean when a coil is not in place. The top of the device features a metal 510 drip tip that can be replaced with any compatible drip tip to suit the user's tastes.
The device comes with spare lengths of resistance wire, spare stainless steel mesh wick and a screwdriver for post adjustment to get you started.
