Well I'm at a loss now, I heard back from the Vendor and from Kanger.
Short MP3 of the gurgling
Kanger tells me this is normal.
The Vendor (I won't mention here out of respect) had this to say:
"You fill up the tank, use it as you normally would. When you left it alone for a few hours or so and pick it back up, there is leakage from the airflow holes. Upon cleaning it up, there is a noticeable "flutter" in the e-liquid when you vape. It may leak a bit during use at this point. If it does not, after some use, the "fluttering" of e-liquid eases down or stops entirely.
Cotton is absorbent by nature and while the cotton may be soaked with e-liquid already, it will still constantly wick e-liquid regardless of how wet it is. Due to the way atomizer heads are designed, the cotton has contact surface with the actual coil that allows excess e-liquid to leak down into the airflow control base where it pools up over time.
The best way to prevent this is to use a higher wattage/temperature for a few vapes every so often so it allows the device to heat up any excess e-liquid that may leak through the cotton. Give that a try and let us know what you find."
I ordered another pack of coils from a different vendor, I am bound determined to make this work!
