Hello everyone, I was hoping to get some input on exploring sub ohm market. I having trouble deciding what to buy.I currently using an istick 30w with a nautilus mini tank for my every day vaporizer. But..... I am split between the ego one and the kanger sub tank mini for my next venture. What would be the better investment? I like the ego because its small, I would have a second battery besides my istick, and it appears that I can use the ego tank on my istick. On the other hand, the sub tank comes with the both the pre made coil and a rebuildable coil???? I think? And I could possible use the sub tank on a mod in the future. Im confused. I need guidance.
