If you are thinking about trying Electronic Cigs, the V2 Pro is the way to go. I have had one since Nov.2014 and I am very happy with it. The battery life is much superior to the smaller cigarette type ones and it holds a lot more e liquid as well.
See what comes in the box of the V2 Pro Series 3 vape pen. Walk through the unpacking of the Series 3 kit; from removing the device to inserting a cartridge. Watch how magnetic fasteners snap the included charging cord and e-liquid cartridge into place, adding convenience and durability to the uncompromising performance of V2 Pro Series 3.
