That's what really irritates me about all of this. One upgrade could've easily made this one of the best tc devices currently on the market.
According to the tests ran by Daniel, the one flaw is that it's not locking and reads the resistance on every fire giving an exponentially hotter and hotter vape every time you fire it.
I will say this though. I vape exclusively on ss 316L and it does ramp down the wattage enough to prevent dry hits on an rba of mine that is notorious for producing dry hits. So, in that aspect it does get the job done, but as far as calling it a good tc device; not even close.
Also, I would be wary of vaping nickel or titanium on it because of the steady increase of heat after every fire. We all know you don't want nickel or titanium going above a certain temp.
