If you are a responsible vapoteur, you will know that heat in your device is something you don't muck about with. Safety should be in the forefront of a vapoteurs' mind.
So, I got a hell of a fright when I picked up my mod and it was HOT! I unscrewed the top and threw the battery out. But it was not the battery that was hot. I couldn't work it out for quite a while. I have less nerves with a mechanical device than an electronic one. I've had a few batteries that have done very weird thing like switching themselves on by themselves.
Vapoteurs must remember never to totally trust their devices. An exploding device must be a truly horrible experience.
So back to my mod. After reassembly - I knew it was not the battery about to explode, I listened and touched and realised it was indeed actively atomising my eliquid all by itself.
