So I have been vaping for over a year now and have tried a few different ecig units there was a very simple starter battery that a friend game me when I first started vaping, could not change any of the setting on it, then went to the Variable Voltage eGo V v2 and then because of the fact that when the battery went out you had to buy a whole new unit instead of just the battery so went to the Joyetech eVic and that is what I am using now. But it has been suggested to me, that the iStick is the way to go, what I would like is to know how it performs compared to a Joyetech eVic. And what models are better then others, this way when it is possible to replace hardware I know if I am going to keep using my eVic or switch. It would also be nice to know how well it it works with Kanger tanks more specifically the Kanger Aerotank mega verses say the Nautilus Mini that was suggested to me as well as being better then the Kanger tanks.
