With inhale activation technology, there are no buttons or menus to contend with. All you have to do is puff on the mouthpiece, which will create a moderate amount of vapour for an RDTL vape that has a tighter feeling draw. You can also find MTL (Mouth To Lung) Xros pods sold separately, if you prefer a more discreet amount of vapour. Xros pods feature a top-filling design and are easily refilled via the filling port located underneath the mouthpiece; you don't even have to remove them from your device when refilling. The mesh build of the coils inside means the e-liquid heats up faster for better flavour. We recommend pairing this kit with 50% VG e-liquid or higher PG options.
