I've been vaping now for about 4 years. Been on and off vaping for a while when i was still using alcohol (stopped drinking 4 months ago) and now i'm making a comeback to vaping,and my collection of vapes and mods are growing (very expensive hobby lol) I have learned how to make my own coils,but still has a lot to learn. I mostly use RDA's and rebuild-able tanks,and also started using pod systems.
