My husband's started leaking a little, which to me was a sign his wicking material was on its last leg so I changed out his pod.
It's likely if yours is gurgling, that is likely a sign it may be about to leak.. I will say it took a good long while for my husbands pod to start going bad, so if you've been using yours a good bit of time it's probably a sign of things to come...
Just make sure you have a spare full of
ejuice and primed with you at this point so your ready for any eventuality, and change it when you think it's time..
