Now that you prime and ramp up as recommended what is prompting you to change coils? Is it a drop in performance or bad flavors, or is it the appearance of the coils?
If it's that the coils LOOK burned or singed but still perform ok then don't worry about it.
Another issue could be your juice. Heavily flavored/sweetened liquids will clog and foul the coil and wicking faster. I've gotten months out of a coil with unflavored juice and the same set-up will go south in as little as 2 days with a heavy liquid, much tastier though.
If the wording of this post seems off: Epic hangover is EPIC!
happy epic hangover haha
Right, it looks burned and it's not going too bad for now defo degrading in taste vapor production!
I've collected super good info on here (thanks everyone^^) so i'm gonna sit on this hald dead coil for a bit and see what else i can achieve with the next one!
