Yesterday I received my Ego Evic-Vt, I immediately had trouble going to temperature mode. I have watched hours of how to videos and when I select temperature mode, it automatically goes back to power/wattage mode. I am using an Ego one mega tank with 1ohm coils. Since I am supposed to be in temp ni mode, hits in power mode are verrry burnt and horrible. I have contacted joyetech and have yet to receive a response. I am desperate please help!!
