Don't know if anyone else knows about this in the newbie area, but you can pull apart kangor coils, clean them, do a dry burn, put them back together and reuse them. I've got 6 unused put away, and I keep using the same one over and over, every 3 days I pull it apart, wash the wicks, dry burn the coil, and keep going. On my 3rd week on the same coil now. Also gives you full vapes, and with full flavor every time. I recommend cleaning your coils every 3-4 days to keep them performing. Google cleaning kangor coils for instructions!
