Important Note: Priming the coil ensures you do not get dry hits or burn the wick within the coil. Failure to do so may result in a harsh burnt taste that will not go away until the atomiser has been replaced.
Take Care with threads: When bringing items together that have threads - back them up in reverse direction until they engage properly, before turning in correct direction to tighten. This will reduce the possibility of cross threading.
