• Cranking it wide open for flavor: That's not how it works. Open airflow gives you clouds, not flavor. If you want flavor, close it down.
• Tightening it too much: If you have to pull really hard and it feels like a workout, you've gone too far. You should feel a slight resistance, not a struggle.
• Ignoring your wattage: Airflow and power work together. Low wattage with wide airflow can feel weak. High wattage with tight airflow can get hot. Adjust both to find a balance.
• Forgetting to clean: Airflow holes can get gunked up with e-liquid residue. A quick wipe every now and then keeps the draw consistent.
