i have the Cthulhu by Deathwish modz. I have been using it for alittle over 6 months and just recently it has been acting up. Plain and simple the mod is not firing. Ive been using the same build since i bought it. I tried using different rdas and still is not firing. I put the rda on a ohm meter and even my regulated mods and it fires just fine. I made sure 100% that my batteries were charged. And have been scratching my head about since. Any help will be appreciated.
