I used to be of the mind (as many others) I had to make coils up "ahead" so to have ready,
but that has all changed... (for Me)
I just make them as I would add juice
I can do it so qwik and low effort, & never any 'failed' coils anymore

my eJuice is pure, clean and easy on the coils (unlike past juices!)
just a matter of a few minutes results in an almost new set up good to go more than a day...
big tanks, big batteries, SS wire, rayon all make for a good life of vapin'
compared to not long ago I had to carry multiple devices to get by...
