Loud zapping Pop sound from a Star Dust? Is that normal

[mojojo]

I have quite a few star dust and only a few will give me that loud zapping pop sound once in a while instaed of the smooth wooosh sound, wakes me up in a hurry then I start checking for cracks but there is none. I know it's normal for cartomizers but is it something I should worry about for the star dust. Could the liquid be too thin or is it certain juice that will do that?

they do it no matter if I use my 1100 KGO or the joy 510 battery


Thanks for your feedback

Just a contented coil's happy farts!

Some of mine do it too. Just there way of making sure your awake. I know they tend to do it more if you accidentally drip some juice down that center hole while refilling.

It's perfectly normal. Nearly all of mine do the snap-crackle-pop thing. Nothing to worry about.
