currently i spend about 25 dollars a week on juice and a coil. the problem is the environment i'm in we do a lot of sanding and dust just gets into everything. I mean i used to wrap my vape in a rag in my pocket but really the tank wont wear out anytime soon and if i drop it in water or paint and rice can't fix it, and the guy at the shop (he does that for free, just likes to help people) cant save it, then it will cost me 35 dollars for another battery. so its an affordable risk.
