iStick 40W TC?

Hi, has anyone gotten their hands on this mod yet?
I came across this giveaway posting and wondered if it's any good.
Would be nice to win but since I don't expect that, I thought it would be a good idea to ask here, so I may order one after the raffle.

Never owned a iStick before, looked a bit too gimmicky to me, but the TC makes me curious.
Is the TC working well, like lets say on the Vapor Flask? Or does it have its problems like some of the early eVic VT60 have had?
Also - are there any known problems with attys? My cloupor mini was my first box and before that I had plenty of mods that had problems with the positive terminal.

Cheers
