Here's the honest breakdown. Some issues are on you, and some are just the nature of disposables.
User error includes things like not charging when possible, pulling too hard, or ignoring airflow blockages. These are fixable.
Product limit means the device is simply done. Disposables have a finite puff count, and when the battery or coil dies, that's it. No amount of troubleshooting will bring it back.
How to tell the difference? If you've tried the fixes above and it still won't fire, it's a product limit. Respect it and move on.
