Leaks are often caused by altitude changes, overheating, or drawing too hard. Store the device upright, avoid leaving it in hot cars, and use gentle puffs to reduce condensation buildup in the airway.

Keep the mouthpiece clean, avoid squeezing the body, and let the device return to room temperature before use. If the device has a silicone plug or sticker, remove it only when you are ready to vape.

It depends on the rated puff count and your usage. Light users typically get several days; heavier use will shorten battery and e-liquid life. Stop using when flavor fades or vapor is weak.
