“suprisingly good flavour that can be achieved with the most simplest of coils, more difficult to wick but very good coil postioning is simple, just make sure its well packed with cotton”
“it's good if you're looking for very restricted airflow as 4mm airflow is very tin and takes damage easily plus if the coil you're using is not high resistance ie 28 gauge or higher you will get a lot of spit back and with a vertical coil that's not pleasant”
