ok I read the topic http://www.e-cigarette-forum.com/forum/new-members-forum/141096-advice-what-buy-newcomers.html about what to buy and would like to know from yall what the best kits out there are, I want a better one for x mass. Ok I have a 2 510 batteries, and a 21st century 2 piece. I am Very happy with them all but the battery life sucks. I hate carrying 3 batteries around but kinda have to keep it small, being a landscaper I cant carry big equipment with me. also i chainvape at home so one that has a passthru would be great. I was looking into this one from Crystal clear vaping, Crystal Clear Vaping does anyone else have this one? Is it powerful? does it last? also i do want everything to be 510 compatable as well. also i do not want any attys, I love cartomizers due to grass and leaves getting in my attys before. Thanks for all yall,s help
