The lifespan of a coil is depends on your vaping habits.Generally you need to change coils every 1 to 4 weeks of usage. If you vape very frequently, you may find that your coil only lasts for between five and seven days. If you vape moderately, it may last you a couple weeks. And if you are a really light vaper, you can probably get away with only changing your coils once every month or so. Yocan Quartz Coils 7 signs telling you it’s time to change your coils.

This burnt taste is a strong sign that you need to replace your coil quickly. Your coil has already gone bad.If you continued to vape with a coil at this point, you run the risk of doing damage to other parts of your vaporizer device. Take the hint and get rid of the burnt taste by replacing your coil ASAP.
2. Vape coil or wick has burned out.
When you find your coil or wick has burned out,you have to replace it,or you can’t get nice taste.
3.Your vape material doesn’t taste the way you would expect it to.
For example,you are vaping an apple e-juice with Yocan Hive 2.0,but you aren’t tasting apple flavor,then there is something wrong with your coil.Change a new coil and try again,most time you can get rid this problem.
4. Your vape device makes a gurgling sound when you vape.
If you start to hear gurgling after a couple weeks of using a coil,we suggest you to change a new coil,that very well may be the problem.
5. Your device is leaking.
A leaky e-cigarette isn’t always the result of an old coil that needs to be replaced. Worn out O-rings or an overfilled tank can also produce a leak and cause e-juice to spill out of your e-cigarette.But it’s also a factor that you should check out when your device is leaking.By taking your e-cigarette apart and examining the coil, you may be able to find out whether or not it is causing a leak.
6. You have been using your coil for an extended period of time.
As we mentioned earlier, coils are not meant to last forever.Using a coil for too long will ruin your vaping experience and could cause big problems for you down the line if you don’t swap it out for a new one.
7. Poor vapor production
When you notice your vapor production smaller and smaller after you use a coil for some time,there maybe many reasons,but change a new coil will help you to find out problems.
Copy from Yocan official site.
When I first got it only 3 coils worked, so I thought it was a goner. Well with rigorous use, the 4th one lit up after a few weeks.
Im still using the first one. When it burns out, Ill put in the spare, and order a 5 pack from here.
Life these days does not get as simple as these machines.
