Try these steps:
1. Check if the battery needs charging (look for LED indicator)
2. Remove any stickers blocking airflow
3. Clean the mouthpiece with a tissue
4. Ensure you're drawing properly - slow, steady pulls work best
5. If the device still doesn't work, contact our support team

A burnt taste usually indicates:
- Chain vaping (taking too many puffs quickly) - let the device rest for 30 seconds between puffs
- Low e-liquid level - check if your device is nearing its puff limit
- Overheated coil - allow the device to cool down
If the problem persists, the device may be defective

MRVI devices are designed to be leak-proof. If you experience leaking:
- Check if the device was exposed to extreme temperatures
- Ensure you're storing it upright
- Avoid dropping or damaging the device
- Contact support if leaking occurs with normal use - this may be covered under warranty

LED indicators vary by model but generally:
- Solid light while puffing: Normal operation
- Blinking during use: Low battery - charge your device
- Rapid blinking: Device protection activated (overheating or short circuit)
- No light: Battery depleted or device has reached end of life
