thing is though if you want more vapor your better off with one that looks a bit like a crack pipe lol, I'll explain what ive got and im faily new to this. I got a cigalike (e cig that looks like a cig) what you want and not enough vapour and harsh on the throat like you said, went back to normal cigs. then got a tank one or carto. All this is, is a cartridge that you fill up with e juice, this burns from what i know better giving you a smother hit and more vapour. first got a f1 which i thought was ok, but have sincew got a ego battery. pretty standard e cig batter for £10 ($15) and a evod cartomisor (cartridge/tank/whatever) for £5 ($8) and it is amazing. Loads of vapour and i get 6mg nicotine so not harsh on throat, honestly no normal cigerretes in 3 months even when i have a beer, cigalikes are a bit pants in comparison.
