Breeze comes with two resistance coils, one is 0.6ohm coil for normal e-juice, if users want to use nicotine salt or high nicotine level e-juice, we suggest the 1.2ohm coil; We don’t recommend the use of normal e-juice with Breeze 1.2ohm coil or use nicotine salt e-juice with the 0.6ohm coil, as the performance may not be satisfactory.
