The replaceable pods are available in two resistances, 0.8ohm and 1.0ohm and feature self enclosed coil meaning that once the lifespan of the coil has been used you simply replace the pod, no messy coil changes. The pods are filled via a silicon stopper on the side making it convenient and relatively mess free.
