Spring is the season of temperature swings. Cool morning, warm afternoon. That matters more than you'd think for a disposable.

Heat thins e-liquid. Thin liquid leaks more easily. So the biggest spring mistake is leaving your vape in the car while you grab lunch. By the time you're back, the liquid has expanded, and you've got a sticky mess in your cup holder.

The fix is simple: carry it with you, or if you must leave it, put it in a bag that's not in direct sun. And when you're walking around, keep it in an inside pocket, close to your body but not against your skin—your body heat can also warm it up more than you'd like.

Another spring thing: you might be outdoors more, and that means more chances for dust or pollen to get into the mouthpiece. A quick wipe with a tissue before you use it keeps the airflow clean.
