I have been getting into the e cig world pretty hardcore now. its become a hobby for me as well as a way of satisfying my nicotine craving. however, I am wondering if i should upgrade to 5v. I have heard good things about the joker and the GLV. What are the benefits of getting a 5v versus an ego model? Any and all differences would be appreciated as i know nothing about these 5v models. can you get them with standalone batteries or do they all take rechargeable? do they hit better? you know what im sayin? im a noob when it comes to this stuff, so any info would be appreciated. thanks
