this is my own opinion on evic vtc mini
i just bought meself the evic vtc mini, purely because of the color option -___-
and yes, it does perform well, with some consideration (adjustment, tweak, etc)
been playing with my vtc mini for a week now, while my previous so-called-TC mod (istick tc40w) performed beautifully out of the box, my vtc mini does need some adjustments.
but it works, despite problems reported on the neighboring thread, i would say that it is not really a problem, but more like differences on how the mod and firmware work (TC wise).
been using only TI wire on:
istick tc40w using NI mode > 0,22ohm 200C > beautiful vape
vtc mini using TI mode > 0,22ohm 250C > beautiful vape with a tad slow ramp up
vtc mini using NI mode > 0,22ohm 175C > beautiful vape
in all three condition of course you can tweak the temp up to suit you
please note that the TI wire i have been using IS NOT the best one, hard to find 99,9% TI in my area (or country), so my wire's TCR may as well been off
