My SMOK stick just started firing up by itself and I didn't touch it ,then it got extremely hot so I quickly unscrewed the coil took the top off it this a common thing ? Meaning I literally st up and as I reached for it it fired up all by itself.
I think it has a 12 sec safety feature. I have the X8 stick which is basically the same thing and never had any problems with it although I rarely use it.
