Hi peoples, kind of new to vaping to quit smoking. Ive gone from a cheapo vape pen to the Alien, my reasons is the variable wattage,hit strength and it gets good reviews. Is there any hints and tips you's can give me and help with e-liquids. Ive been told there are certain e-liquids which i shudn't use because of heat and burning the coil/wick etc, can anyone explain why ?. Is the tank ok or change to another better .
