You'd think regulars would know this by now, but even experienced users make mistakes. The biggest one? Keeping the airflow tight all the time.

Sure, a tight draw can give a stronger hit, and some people prefer that for indoor use. But on a hot day, that tight draw works against you. The vapor gets hotter, which can feel harsh on the throat. And the pressure buildup increases the risk of leaks.

Another mistake we see: ignoring the airflow when switching from an indoor to an outdoor setting. If someone's been vaping in an air-conditioned office all morning, then steps out into the sun, they need to adjust. A quick twist of the airflow ring makes all the difference.
