Hello. I just bought an eleaf melo2 from a friend. I have been messing with the settings and am not sure what I am doing. I don't have an instruction manual or anything. I'm not even sure the type of coil he put in it. I am using it for cbd oil. I don't understand the wattage and temperature....from what I have been reading on Google it's a matter of personal preference. And this particular model apparently works best at 60w but from what I understand that will blow through my liquid quickly. Can you help me out with a good place to start?
