Was the 40TC Eleaf's first foray into TC?
Was it JTech's? (eta: no, they had the eVic VT about that time, not sure what else)
The 40 was 9 months ago (or so) and the "comeback" from the i50 debacle.
I got one then and haven't had any issues, though the TC is, as said... lacking.
Activating the Titanium mode gave it extra life though, and it's still a nice 40w.
The same generation i100 is still plugging along nicely as well.
Starting with the VTC, JoyeTech/Wismec/Eleaf have really found their legs for value and features. We've seen some hiccups, and some units will fail, but by and large... they're proving to be very good value for the money. And they seem to be leading the industry for features and upgradability in the lower price segment.
Perfect and/or investment quality? No.
But I have no qualms about this new one (other than the two I posted upthread).
We know the TC works on the previous mods in this stable. I expect the same here.
