Just yesterday, I purchased a Cool Fire IV off of my friend, with an Aspire Mini Nautilus atomizer attached to it. I used it for a few hours, until I noticed the wattage was very high and each hit was getting very hot. I later emptied the juice out of the atomizer.. After that, I pressed the fire button and a ton of vapor with a burnt smell began to come out of the atomizer, despite the fact that it was empty. Any suggestions? I ordered a completely new atomizer.. This is also my first vape, and I am not too shabby on the subject.
