The V2 Cigs EX Series features an upgraded rechargeable starter kit offering stemming from the widely revered and accepted classic version. V2 Cigs has always been a brand of innovation, perhaps much more than any other company. Thus it wasn’t surprising to catch wind of V2 coming out with an upgraded version of their flagship rechargeable line. The EX Series is slightly more expensive than the classic series, but features almost twice the battery life and more advanced/higher performing cartridges. It’s also worth noting that the EX Series is a much more sleek and sophisticated design made of higher grade materials. Lastly, the EX Series offers a variety of sleeves to lend you either even more sleekness or a bit of trend to boost your style.
