“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.”
“Very good coils but don't last as expected - 3 days in average. I am not a heavy vaper and the liquid I am using is 75% PG - I would expect them to last a bit longer.”
