I have come to love the sound of the snap, crackle and pop of the juice hitting the atomizer. I feel I can tell if it is going to be a good hit or not from the sound. Usually no sound means a slim or cool vape or the cartos getting old. Also seems even in the some brand some hit better than others and the juices do make a difference in the sound. It is just music to my ears. Still using an ego until other equipment makes it next week. Can't wait to hear the sound of higher volts burning up the juice, just below the burning stage. Like my vapes extremely warm so hopefully there will be more snap, crackle and pop next week.
