BLECHHH! Why would you use the same coil for that long? Just to see how long they last? I change mine after every 30 ml bottle of juice and that is probably pushing it. Just because the coil lasts don't mean you should be using it that long.
You hope it's ceramic.
I've been around for a while, it is... Dries awfully fast, doesn't retain flavor, and dry burns easily. Rayon would have turned to ashes by now, as well as polyfill
Thats just plain nasty and unsafe, at $ 9.95 for 5 coils, why chance it?
Juice, coil temp are variables. I have experimentally soaked mine with a 48 hour air-dry. They didn't have the old flavor, but, vapor production was off a bit. Maybe I should try different solutions.
I only use them for 30ml juices currently. If I know I am only going to do a 15ml or less bottle, I use a rebuildable.
What kind of juice are you vaping?
I get about 10 days out of mine.
I know of a few HH .357 that have been going for at least a year...
