This kit provides a new touch to the squonking style of the vape. It supports three kinds of batteries: 18650/20700/21700. With the 21700 battery, the device is able to fire up a wattage of 150W. You don't have to carry an e-juice bottle with you as you can just vape from a dripper. Keeping the wick wet is a good thing. Overall, a good experience is offered.
