How long did the mega BCC last before dying? I know its not what people want to hear, but clearomizer coils on average do not last longer than 2 weeks for most vapors before you need to either replace or rebuild them. For some heavy vapors even after 1 week. So that is the nature of the beast. But compared to the cost of smoking (in terms of money and health) there is no contest, even when replacing a coil on a weekly basis. This is of course when vaping on only 1, maybe 2 devices. Many of us have 3 or more devices that we use, so in terms of time, coils will last a lot longer.
It all comes down to how much time you have to mess around with the coils in terms of boiling, dry burning, etc. to increase lifespan with a few days
versus convenience
versus budget. It's all relative
