“Work fantastic compared to competitor price. All above reviews below 5* refer to using 70-80% VG when the coils are best used at 60% max... Try using a 50/50 liquid, work like a dream and mine seem to last for a good couple of weeks before needing to be changed (I’d say I vape quite heavily too).”
“Using these coils with my Innokin T20-S, they don't saturate very well with 80/20 liquid but 70/30 seems mostly ok. Would be better with larger wicking holes but once they are saturated (takes a few hours) they do the job and last a decent amount of time.”
