What I'm using now is a vapage VPro650. Since I have taken to it so well, I think i should start looking into one of my choosing (as this one was a 2nd hand thing). I love teh feel and taste of metal (I"m weird, I know) So I'd like a metal/aluminium e cig that has a tank that I can see into (so theres no guesswork for how much is left). ALSO, it's gotta be on the cheap end of things cause I'm still waiting to get on disability so ill have to do some mowing and oddjobs to get it. Any suggestions? Or, if youve used this particular model, is it long lasting enough that I should just get a 2nd battery pack for? Any advice/recommendations would be super helpful. OH OH also, a question. With e-juices I know theres two types. PG and VG? Do i need to make sure which one this takes or are they compatable with all of them and are just different compositions?
