I've had the eVic-VT for a few weeks now, started on the stock Ni coil using 50/50 juice, no issues other than the coils do seem to get gunked up rather quickly. Switched out to the Ti coils, similar results with a cooler more flavorful vape. I don't think the small juice holes on these stock coil's will work very well with max VG juices. I've read people in this forum bashing the Mega One and I honestly think that for the price it's a pretty nice tank. To each his/her own with this stuff but the Mega One has not leaked once on me and gives a nice satisfying temp controlled vape, will try my hand at the CTR-Ti heads next. Once the Ω's are locked in at room temp, I've had zero fluctuation and it performs exactly as it should. I just built a 28g 8 wrap 3mm Ni200 coil, locked in at .11Ω on my Subtank Mini RBA, vaping sweetly at 480˚F 30w. I've had no anomalies and it stays in VT mode. One complaint I do have with mine is that the Control Knob feels rather loose and flimsy but functions perfectly. You can pick one of these up at VAPENW for less than the price of a carton of cigarettes.
