I have been having trouble with my iStick 30 watt saying "atomizer short" I took it to the shop he said it was build up on the threads I also read online and loosened the tank (thinking I had it on too tight) and cleaned all threads in case it was not getting the proper connection. It wasn't working today, kept saying "atomizer short" and the battery was low, I plugged it in the laptop to charge it. an hour or two later I unplugged it, put more juice in it and tried using it only to find, you guessed it "atomizer short" I admitted defeat and put it on the table, I went to pick it up later and the box is really HOT! I took off the tank, tapped the button 5 times to shut it off but it's still really hot. does anyone know what i can do? I really don't want this thing to explode... wtf?
