Agreed on the d2...plenty of power, temp control, great build quality and the form factor is great, almost too small. I picked up a evic VT mini today, and I have a feeling it is going to #1 in my rotation!! 60w, temp control, great screen and easy to navigate menu. Replaceable 18650 as well as micro USB charging with pass through...build quality is on point, form factor is similar to the d2 but slightly larger so it's a perfect fit if the d2 seems too small. Wish I had bought one sooner, this thing is killer!!!!
Left to right for comparison to other popular boxes....
Sigelei 150-Snow wolf 200w v 1.5-Sigelei 75tc-joyetech vtc mini-p4you ipvd2-
Hope this helps, I truly feel that just about any vaper would be happy with the vtc, from newbs to seasoned veterans.....
EDIT: The vtc also comes with a ego one mega tank w/ ni200 and kanthal coils. I don't care for it, but with your current equipment I know you would LOVE IT, especially using the ni200 tc coils...
UPDATE: I put the ni200 coil in the mega tank, and filled with max vg. While it's a little tighter draw than I normally like, the flavor is Great and the vapor production is actually pretty impressive . I will probably rock it on the evic from time to time, maybe carry it with me loaded with a different flavor than the Herakles as a back up. This is probably my best vape purchase to date, thinking about buying one for backup, and one for my wife and father who are both rocking 30w isticks....
Here it is with the ego one mega tank..
