Smok Nord Coil
The 0.6Ω Sub-Ohm mesh coil is specially designed for sub ohm vaping, it has a large mesh inside, with which you can get faster heating process and massive vapour clouds.
The 1.4Ω MTL regular coil is designed for MTL vaping, you can enjoy throat hit with it.
The 1.4Ω MTL Ceramic coil is designed for MTL vaping but works better for those who like to chain vape a little. This is due to the ceramic material coping better with higher temperatures that might be seen with heavier vaping. Many people would use CBD ( Cannibidiol ) Oil and many would use Nic-Salts with this coil to get a longer life out of the coil as both of these e-liquids tend to burn the coils out sooner than regular freebase e juice.
