Using this atomizer with a nicotine level above 6mg will usually taste burnt or harsh.Warning: This tank uses sub-ohm resistance coils. This tank should only be used by experienced users. Extra safety precautions should be practiced when using a sub ohm tank. This tank will only work on a mechanical mod or a regulated mod capable of firing sub ohm atomizers and coils. For example, if you have a 0.2ohm coil, your mod must be able to fire atomizers of 0.2ohm or lower. You must be also ensure that your batteries can handle sub ohm atomizers and coils. If you're using a regulated mod, make sure it can handle the amps. Improper use can lead to injury or damage. For mechanical mod users, please use 20 Amp batteries or higher. Use the OHMS LAW CALCULATOR, CHECK YOUR AMPS, and be safe!
