What carries over from these fixes: most gurgles are surface-level and fixable without opening anything. Always start with the least invasive steps—flick, shake, dry puff. And pay attention to how you're storing the device. Temperature swings are a commuter's worst enemy, so keep it in an inside pocket where it stays closer to body heat.

Also worth noting: if you're on your last puffs anyway, a gurgle might just be the device telling you it's done. Don't force it. You're not saving money by squeezing out a few more hits if it ruins your jacket.
