Put a single coil in which came with the recurveThe coils that came with it are fine to use, you might as well try them first seeing as you already have them before buying anymore, see the coil a few mm above the airflow and be sure to fluff up the ends of your cotton before you tuck them down into the deck...
Have bought a pulse 80 so I know it’s regulated and safe
Vaping at 45 watts, Wow, awesome flavour, really like it
Thanks for your kind help, much appreciated
