Two types of resistance coils to match your preference:

• 1.0 Ohm: suitable for MTL, recommended for 40-50VG ratio e-liquids.
• 0.6 Ohm: suitable for DTL, recommended for 40-60VG ratio e-liquids.

For best experience, we recommend replacing the coil after every 3-5 full tank refills, or when changing flavours.
