Hi guys! I am new to vaping world and just ordered Provari Radius and Kabuki P3 tank from official web site. There are tons of information out there, so I am a bit confused. What else do I need to order? I understand that I need coils (what kind of coils?) and e-liquid juice. What are the best juice brands? Do I need anything else to begin with? Some maintenance or cleaning supplies? Thanks for your help.
