How can I tell if my coil needs to be replaced?

At some point or another, you're going to have to replace the coil in your vaping device. The hard part about that, though, is that some people aren't sure when they need to replace it. Sometimes it's obvious that it's time to replace, while other times it's just subtle things that you might not even give a second thought to.

If you can't really taste the flavor and you're mostly tasting something burnt, then it's time to replace the coil. The next sign is if your e-juice tastes different than it's supposed to. For instance, if you have a strawberry e-juice that tastes different than it used to, then that could mean the coil needs to be changed.

Another sign is if your device is making a gurgling sound when you vape. This isn't normal, and it could be pointing to a bad coil.
