i got my first rba and i am going through more juice than i used for my carto tanks. its a cobra clone from FT. its only been a couple days since i got it working better than the carto tanks. first day i got it spent all my free time watching videos, modding it and making coils. went from 3ml to 5ml per day and i dont think im using it more than normally. is it the norm for rba's to use more juice than other atomizers?
