One of mine behaves the same way. Once it has less than 1 ml, it occassionally gurgles. Also, if the battery is low, it builds up more fluid.
The juice I am using with it is 70/30 PG/VG, which is the highest VG I have. I've vaped over 30 ml on it already, and it is missing one of the loose wicks. It only leaks really bad when it is below .5 ml and the battery is low. I have spare coils, but I wanna see how long this old coil can make it. I also have a spinner coming tomorrow so I wanna see if 4.2+v helps.
