Kanger T3'D Bottom Dual Coil Clearomizer
This bottom coil clearomizer is made by Kanger. It has replaceable heads and takes 2.5ml of e-liquid at a time. With a bottom coil you get warm vapor which has a really clean flavor that does not cause the wicking issues that other designs can have. It fills form the bottom so if the head stops working when there is liquid still in the tank it can be easily replaced without having to drain the liquid out. It is very easy to fit, just unscrew the bottom atomizer head hold the tank upside down and fill with liquid and then screw the head back on. It is worth thinking about getting a purer flavor as that means that you can fully enjoy the e-liquid that you buy as it is supposed to be tasted. Being simple to use, also means that you do not have to worry, even if it is different to what you are used to.
