Hey, ECF I tryed to do a search and couldn't really find any info on the topic. I been vaping with ecigs for about to weeks now and just received my Volt 65mm.. Very happy with the product but I do find it has a lot of air flow and whistling sound when drawing. I was able to find something in a threads about blugging one of the air holes with a toothpick. I did so and found it to help dramatically but still have some air flow and whistling sound going on when drawing vaper. Could this be caused by the carto? Any tips other then the toothpick to help cut out the air flow? Any info tips would be great..
