The Joyetech eGo Twist+ Starter Kit is a great little kit for beginners. It pairs a variable wattage twist battery with a Cubis D19 tank.
The wattage is adjusted via the twist wheel at its base from 5 watts to 30 watts and packs in 1500mah capacity.
The Cubis D19 tank is a top-filling tank which uses the Joyetech Cubis / AIO Coils, including the 0.25 ohm Joyetech Notch Coils.
