Exactly the way mine works. Running Ti in Ni mode seems to work better but straight Ti or Ni builds all suffer from that anemic vape syndrome.
I am going to the B&M where I picked up mine tonight and see what they have found out from suppliers. They will not refund or substitute so if anything I'll pick up another VTC mini with a different batch code and see how that works out. It will be good or the same and if it's the same I'll live with it and wait for a fix.
I bought this from a local B&M, you know supporting the local vaping economy and all that drivel. Buy local you'll get support they say... If this was a $30 mod where the TC didn't work quite right it would be no biggie for me, but with our Canadian dollar sucking the hind teat these days, I stupidly paid a lot more for it than that.
If I don't get a replacement or something tonight then that will be the last dollar spent in local B&M's for hardware.
Fingers crossed I come home with a shiny new black one that does not have this issue. I'd take another white one but their black versions are from a newer shipment, with my luck the newer shipment will be from a surplus of older product...
