You'll love the Dura-C as myself and many do. Nothing like having the control over the length of hit and heat over the chancy auto switch batteries.
And with the Dura-C you can direct drip on the atomizer and use an empty cart if you wish (since the battery is sealed and removes the chance of flooding it with juice).
Welcome to the esmoking addiction, lol.. save your penny's now cause you'll be like the rest of us and just "need" to buy all the accessories out of "want", haha.
