Reliable mod for beginners and experienced vapers

I bought this for my sister as an incentive to stop smoking. I've been through a few mods and tanks myself but find this one to be a pretty reliable starter kit for a beginner, but also suitable to carry on for more regular/experienced vaping as well. Quick postage and helpful service. Thanks guys! (And she's been off the cigs for the first time in 35 years from the day it arrived - win!)
