I wouldn't dismiss his concerns. I need far more information before I decide one way or another. I also want far more information and field reports from users before switching to a temperature control mode.
I am going to avoid nickel altogether due to it's carcinogenic properties. That is enough for me, not to mention the lack of resistance which is a real danger.
I also saw some talks about the disadvantage and worries about Ni200 nickel material used on temperature control coils. The Ni200 nickel can not handle the high current,it requires a little bit of "break-in" otherwise it tastes a little off at first. Some people worry about the presence of nickel oxides formed through thermolysis may be inhaled and cause lung lesions.(Ni200 heated to 400 degrees Celsius which would be 720 something Fahrenheit in the presence of oxygen creates nickel oxide.)
I've tried the TC function using the Kanger Ni200 and I have to say, it wasnt as enjoyable as I assumed it was gonna be. Vapor is more or less the same as the khantal however taste wise, I couldnt really get the same level of flavour from the khantal. I was using it at 430 F. One good thing though is that I was able to do my long inhale on the nickel which I couldnt.
I haven't tried Ni200 setup's. But this information has caused me to stop and think, because he does bring up some valid metallurgical concerns.
