Think of the wick, coil, and airflow as a team. The airflow pulls air across the coil, which cools it slightly and carries the vapor. If airflow is restricted, the coil runs hotter. If the wick is dry, the coil runs hotter still. And if the liquid is thick from cold, the wick stays dry longer. One problem feeds the next.

For example, on a freezing morning, you step outside, pull hard because the vapor feels thin, and the device compensates by heating more. The wick dries, the coil overheats, and you get a burnt hit. It's not a defective device—it's a mismatch between usage and conditions.

So the fix is to break that cycle: warm the device in your hand for a minute, take a couple of gentle priming puffs (without firing, if possible), and then vape normally with pauses between puffs.
