Pack of five replacement coils for the Innokin T20-S starter kit. 
Note: These coils will not fit the T18/T22 starter kits, or any other atomisers.
These replacement coils come in two varieties -
High Power - 0.8ohm
Low Power - 1.5ohm
The excellent T20-S starter kit comes standard with the higher-powered 0.8ohm coils, which are more than suitable for anyone looking for a warm, satisfying vape experience.
But if you prefer a lower, slower vape experience more akin to a cigarette, then give the 1.5ohm coils a go.
If you are vaping more VG-heavy (80%+) liquids such as Rasmus, we have tested and would recommend the 0.8ohm coils.
Usage:
Each coil should last you between 1-3 weeks, depending on your usage. There is no real sudden "cut off" to when you should change coils, but you'll notice the flavour and vapour production start to taper off - really, it's a matter of preference. 
To change your coil:
Remove your tank from the battery.
Unscrew the bottom ring from the tank.
Slide your old coil straight out.
Insert your new coil.
Replace the bottom ring on the tank.
To refill your tank:

Unscrew the top cap.
Fill against the side of the tank, leave a little bit of space.
Drop two or three drops of e-liquid down the center of your new coil, to help get the internal cotton wet.
Screw your top cap back on.
At this point, we recommend you give the tank a few short inhales (without pressing the button) to make sure that the liquid has definitely entered and saturated the internals of your new coil.
Wait 5-10 minutes before vaping.
Done!
Note:
In colder climates, your liquid may thicken slightly. If this is the case, we recommend that you leave the new coil to soak in your e-liquid a little longer, and once you start vaping, take small short inhales to ensure that you do not accidentally fire a "dry" coil.
