KangerTech CE4 Clearomizer
The original and still one of the best, the CE4 clearomizer from KangerTech is the workhorse of the vaping industry. Designed to produce a lot of vapour, the CE4 holds 1.6ml of e-liquid. Plus the 510 thread means it is compatible with loads of different types of battery, including eGo, eGo-Twist, etc.
The CE4 gives a really realistic vaping experience, which is due to the FAT wick that soaks up your e-liquid and gives a really even distribution to the coil. Currently this product is only available in clear, either individually or as a pack of 5 pieces.
