I’m very satisfied with the 510, but the batteries don’t last very long with my smoking habits. I would like to try a higher voltage mod for more throat hit, vapor and extended battery life, but this subject is very confusing to me. I read about the Silver Bullet, Prodigy, The Chuck, Bartleby, eGo, Janty Stick, Chameleon, Juice Box, Black Beauty, Screwdriver, Nicostick, gosh, the list goes on and on. I guess to narrow it down, I would like to keep the look and feel of a traditional cigarette that would last all day and provide a bigger throat hit and more vapor that I can use with my 510 under $75. Right now I’m considering The Chuck, but any suggestions would be appreciated.
