I started w/e-cigs from Vapor4Life back in Dec.2012 and found out I love vaping. Then I found that tanks lasted longer for my chain vaping habit, so currently do that...and feel like I've mastered that. Then I just got an adapter to try out clearomizers. But I just wanted to know, since I'm just slowly moving up the vaping ladder...what mod or product do you recommend as a next step? I'm still learning, so want something easy to use, easy to fill and understand. (I'm still confused about voltages, mahs and the such). You know what I mean hopefully? Thank you for any recommendations.
