I see.. But how would you know when it's bad?it kind of depends on the kind of juice you like. Some darker or sweeter juices can clog up a coil faster than other juices. Most people can get anywhere from 1-3 weeks on a coil.
The flavor will start diminishing, tasting muddled, or even somewhat burnt. Just be sure to properly prime the coil prior to use. Put a few drops on the wicking material in the coil, fill the tank, let it sit a few minutes. Take a few puffs without pushing the button and you should be good to go.I see..
