These are genuine Notch coils by Wismec/Jaybo. They feature a 1-piece design and look amazing. The coils are constructed from stainless steel, provide a more even heating area, provide flavor and make rebuilding easier than ever.
What really sets the Notchcoil apart from a tradional clapton coil is that vapor is produced at lightning speed, as the ramp up time has been virtually eliminated. The Notchcoils also make rebuilding easy and leads are soldered. They fire with a resistance of 0.23Ω.
Overall, these Notch Coils were designed specifically to tightly fit the Theorem deck, so don’t buy cloned or similar Notchcoils from other manufactures!
