Had my 350 for several months now and have been very happy with it. However, a few days ago it became possessed by some sort of demon. The readout will just turn on by itself and the watts will slowly tick down until it gets to 6.5, and then the screen will just stay lit up until you do something. It has done this while both sitting overnight unattended as well as in my hand in the middle of a drag. I tried changing atomizers in case something with the resistance was causing it. I pulled the batteries completely and let it sit for almost 2 days before trying again with the same results. All four batteries are sister-wives, bought new together and always used and charged together. I tried another set of batteries, same results. Anyone else have this problem, or do I need an old priest, a young priest, and a new mod?
