I like the VT but mixed feelings about the TC side. When it works is a good vape but if I put it down for a few minutes goes berserk, TC kicks in and vape is super weak. Only workaround is to remove the atomiser and hope that the APV will allow to be reset. I hope they had implemented a way to force reset without removing the atomiser.
In VW mode works really good with Kanthal so I might drop the whole TC thing for now.
Worst part is that now they will correct the issues we have and I get stuck with current firmware.
Lots of peeps complain about tc not working properly only to find out later it was their build or intermittent connectivity within their atomizer. Tell us more about your setup, build and symptoms. Odds are the source of the problem is not the VT.
