Nautilus 2

Hey, guys!
I've bought an eleaf Aster with a Nautilus 1 head, which got lost. As I was very happy with it, I bought a new one, this time with a Nautilus 2. The first time I filled it, it was leaking through the Airflow holes, so I brought it back to the vendor, who said, that the coil was damaged. He changed it and charged me for a new one. Yet I've tried it with three other coils, but it is still leaking from time to time, so my question would be: Am I doing something wrong? Or is the product faulty?

I examined and cleaned it thoroughly, but it still does it from time to time.

Hope you can help me, because I really like it.
