The eGo-C is the latest addition to the eGo range as of early 2012. It features a unique changeable atomizer which means that you do not have to change the whole of the top part of your vapourette electronic cigarette but only the atomizer head which essentially is the main part that creates the vapour.
The top part of the eGo C Atomizer is made of 3 parts:
The cone part that houses the atomizer head
The cone base that attaches to the cone from one side and the battery from the other end.
The atomizer head which is the main part that creates the vapour.
In the long run, all you will need to change is only the atomizer head as the other 2 parts are mainly cosmetic and static. Given this. The atomizer heads are almost half the price of a standard eGo-T atomizer.
These atomizers do no leak and are quite reliable compared to other atomizers on the market.
Remember the key to vaping / electronic smoking is to take slower & longer puffs / drags.
