Hi
@EllsAppoc and welcome to the planet.
If you bought the kit which comes with a tank then you would of received a 1.8ohm coil and a 0.7ohm coil.
your screen should be set to wattage mode only.
dont use voltage/bypass or TC these are settings for more advanced users. ive been vaping 9 years and never used these either.
1.8ohm coil should be used within the range that shows on the coil. usually around 9watts-14watts max. (video below says it comes with 1.6ohm coil which runs at 7-11watts).
the 0.7 can be used between 20-25watts.
as said a burnt taste means youve burnt the coil out and its ready for the rubbish bin.
As John said above, bedding in is a must. drip juice on all the cotton holes around the coil first then once tank is filled start low. so if its the 1.8 or 1.6 coil start at the lowest wattage setting and then turn up a watt every couple of puffs. starting at the max wattage without priming the coil is the best way to burn it out quick.
Oh heisenberg, decent but the flavour you will never get rid of. once used in a tank no matter what flavour you put in afterwards heisen will always be there. tbh this flavour needs a tank only for that flavour.
me cant stand salts so have never heard of drifter before so no idea how strong the flavours are. salts are very smooth but using at higher watts might give you nic sik where you get dizy or feel sick. nothing to worry about but stop vaping for at least an hour. salts are best used with mtl mouth to lung coils so best with the 1.8ohm.
