The Vaporesso XTRA Pod Kit features a plastic refillable pod of 2ml juice capacity which have internal coils, saving you a bit of money in the long run. Referred to as the Unipods. these pods are completely refillable and last an estimated 14ml of juice before burning out. The pods for this kit are available in 0.8ohm mesh and 1.2ohm regular. Both Unipods have amazing flavour production with a super smooth hit, if you prefer a more powerful hit we recommend the 0.6 Meshed Unipods, otherwise the 1.2 regular Unipods are much better suited for mouth to lung.
