I have a ehpro Raptor tank that uses its own coils as well as Horizontech falcon king coils. The flavor is amazing, best I’ve had period. It’s on par with my beloved profile rda which I thought impossible from a factory coil tank. My problem is these EHpro coils don’t last very long. The start leaching dirty juice into the tank turning my clear juice dark after a few days and it’s not long after the taste starts suffering. I’m hoping the falcon coils last longer and I still get that excellent flavor. So for those who have used these coils, how long they last you? Also I’d like to hear if you have any other pertinent information about these coils.
