Hi, I recently purchased an istick TC40W and an iJust 2 Atomizor and am EXTEREMELY happy with it! But when I change the temperature setting and vape at say 220C it will automatically sent it at it at 20 watts. It gives me the option to change it but if I go back to the temperature setting and change it up or down even in the slightest it will then again default at 20W. I REALLY enjoy the feeling of the temperature and when it goes to the wattage mode it doesn't stay at that temperature. The manual wasn't very through so maybe I just don't know how to use it. I have never used an electronic cigarette that had a temperature control function so I probably am just ignorant as in how to use it but I NEED to learn.
