i started out with a cheap e cig also that i bought from a local tobacco store. the e cigs were E Health Cigarettes, they were crap and lasted maybe a week and when i took them back to the store the guy pulled out a box full of parts and said, please find what will work....lol. well i wasnt loling at the time so i started doing more research which lead me here. everyone here will help to get you the right info on what your looking for, they sure did help me thats for sure .
i would get a new e cig, thats what i would suggest. maybe a 510 starter kit which i have or a eGo which is very popular
