Mods were originally named in a past-time of the electronic cigarette industry. The name sprouted from vapers manually modifying different devices to create increased performance and battery life that manufacturers didn't offer at the time. Fast-forward year's later and manufacturers are producing outstanding, well performing and long battery life mods that most advanced users flock to.
Though an e-cigarette Mod may have been originated by advanced vapers, many new vapers are starting out with these Mods due to their increased performance, long battery life and included safety features. If you're wanting an e-cigarette that has safety features, battery life that will hold you over for a full days time, along with advanced performance, a Mod will certainly do the trick!
Note: Being there is no circuitry, Mechanical Mods do not offer safety features.
