I had forever ago bought an aspire nautilus mini, and have nothing but great things to say. Best clearomizer I've ever had. A buddy of mine just recently purchased one, and the airflow was so tight, and then the gurgling and spit back, and it was horrible... I took apart the atomizer, only to find that it looked as it should, and even tried the other coil, to find the same effect...anyone know what is causing this? How to fix?
