Mechanical mods are the most basic but most advanced mods at the same time. Tube style mods are generally extremely durable cylindrical devices where the firing button makes direct contact with the battery, as well as some more box mod style devices where the firing button completes a simple circuit in either parallel or series configurations.
Because of the direct contact with the battery there is no chip or safety mechanisms in place, meaning they will fire anything thrown at them, which can make them dangerous if not used correctly. However, when used correctly, mechs produce some of the best flavour, vape production and hits that money can buy!
Please note: Mech Mods are unregulated devices that should only be used by experienced vapers & builders with an understanding of Ohm's Law
