The Smoktech Magneto Mod is a fully mechanical, stainless steel, telescopic advanced e-cig mod with a spider logo on the end cap. Instead of using a spring, the Magneto uses a magnetic switch. Inside the switch there are two magnets with the poles facing each other on the bottom firing unit. This creates resistance to emulate a spring, but without a spring to wear out, the mod will last longer. The switch also has a reverse threaded locking ring to prevent the unit from firing when not in use.
