Titanium is 0.0035 so 0.004 is going to overheat the coil a bit. Then again the Smok XCube 2 set to the correct 0.0035
underheats the coil (requiring a +20°C-30°C offset in my experience thus far), so maybe it'll balance out to 0.004 being right on the Mini
I am tempted by this, because if they in future FW updates deign to lower the TCR to at least 0.003 that enables accurate Resistherm (0.0032), and if they would go to 0.001 (as they are rumoured to be doing on the XCube 2), then that's SS.
Though SS support would require the resistance reading to be milli-ohm, 0.001Ω, and if it really is a re-badged/hacked-up version of an older mod, then it probably won't be.
Hmm, $35 on FastTech, and with no battery it ships fast. That is pretty tempting actually. I just cancelled a $20 delayed atty on FT so I have a gift certificate and will be placing another order, so I can see this falling into my basket accidentally

Worst case I always need to use temperature offsets on it, but I do that on half my mods anyway.
