For Advanced vapers.

You must have intimate knowledge with using multimeters; be well versed with Ohms Law and battery safety and how it relates to wattage and voltage; be well trained in building coils and how to properly configure them; and have a solid understanding of electronics in general.

Prior to purchasing and using any wire, you must make sure that you fully understand the following:


  1. All rebuildable coils must first be tested prudently with a proper meter prior to it being used, as untested atomizer coils can be extremely dangerous.
  2. Coils that have been improperly configured or are otherwise faulty can blow your electronic device, which can result in serious injury to you and/or your property.
  3. Coils that have been newly constructed must be tested on a meter, then first used on an advanced personal vaporizer (APV) that has all of the appropriate safety features, including short-circuit protection. Once the atomizer coil has been tested and used on such a device, you can then cautiously use the coil on a mechanical MOD.
  4. Faulty or otherwise improperly configured rebuildable atomizer coils can damage electronic devices, which can result in bodily injury or harm.


By purchasing and using this product, you hereby consent to wholly taking full responsibility and sole liability for the purchase and use of this item. You further agree to hold all liability for the usage of this product.
