You tightened the tank until your fingers hurt, checked every seal twice, and somehow your vape is still leaking all over your pocket. Frustrating, right? The problem usually isn't about how tight you screw things together. Temperature changes make the liquid expand and contract, which pushes e-juice through even microscopic gaps. If you bought your device from a Smoke Shop Fort Collins CO, they can show you how coil position and airflow settings affect pressure inside the tank. Sometimes the O-rings are just worn out or you're using juice that's too thin for your setup. Walking into a Tobacco Shop Fort Collins and asking someone to inspect your device takes five minutes and saves you from wasting more liquid.
