There are many, many devices and attachments out there. Many, many, many. None are perfect, and arguably none of them will be the only device that you will need or want.
Please listen to what Grimm Green, one of the most widely respected reviewers has to say about the Joyetech eGo-C Twist.
THE EGO TWIST IS A GAME CHANGER - YouTube Grimm Green Twist Game changer
Some people say that you, or a typical beginner, will be too confused by the knob on the bottom that you turn clockwise for more voltage (and therefore more watts, or heat, at the coil that vaporizes the e-liquid/juice), and counter-clockwise for less. I give you, and them, more credit than that.
The Twist is the recently-released "next generation" of eGo-class device, a class that I believe was started by Joyetech, which is a Chinese company with a very, very good reputation for products of very good quality and reliability that are sold at a fair (IMO) price. For the first time, it offers variable voltage in an eGo-class device. Variable voltage allows you to adjust the amount of watts sent to (or generated by/within) the coil (the coil is the working part of an atomizer).
The kGo, Riva, Joyetech eGo-T, and Joyetech eGo-C batteries are fixed voltage. I see no compelling reason to start out on fixed voltage now that the Twist has arrived on the scene. I have received quite a few responses, but I have found none of them to constitute "compelling reasons" to start with fixed voltage
if you do not require a ciggie look-alike.
The 650mah Joyetech Twist is about an inch longer than a 650mah "regular" xGo battery. To me, that's fine, since I think they're a little on the short and stubby side in the first place.
That decreases battery life somewhat, since the 650mah Twist is about the same length as a 1000mah "regular" xGo battery. My solution: get three Twists as soon as you can, or just two and keep a charger handy. You can get a USB cigarette lighter adapter from Walmart that has two cigarette lighter outlets and two USB outlets.
I have heard that "you don't need variable voltage". True; and you don't need your legs, either. But they're nice to have.
They cost $22 each. You'd have to buy a charger (two pieces), a drip tip, and some cartomizers. I like Boge 2.0 or 3.0 single coil stainless steel XL's, that you could use as-is or punch or slot to use inside a Smoktech 3.5ml DCT tank. I also like the Vivi Nova atomizer tank. Oh... get some juice, too. Tobacco flavor: Backwoods Brew "Virginia" or "Casablanca". Non-tobacco: Backwoods Brew Root Beer or Peach. Vape these while you explore other flavors.
