Great you have been ash free for a year.
What mod do you have that can fire
coils with that wattage? I saw in the link 400w. Im curious now, never heard of a mod that could fire a 400watt coil. So the mod woul be capable or rated well higher than 400 to fire a 400 safely. Don't doubt it if they sell those coils something must be able to fire them. Got any pictures of the mods?
