Got my reliant in and I think it's borked. Keeps reading my ohms to high. It displays 0.32 and 3 other mods show 0.22 and 0.23. Tried 2 different tanks with the same Ti build with the same results. Guess I'll see how their customer service is.
Right, I've been meaning to post about this.
My Reliant also developed exactly this problem. A likely solution is to carefully tighten down the nuts holding on the top plate - there are three, requiring a 1.5mm hex head.
On mine I tried to remove the three nuts so as to lift the top plate and check underneath. I could not proceed however because one of the nuts was stripped - stripped before I even started trying to turn it, and then made worse when I did. I tried for literally hours to get it out, using various methods I looked up online. Eventually I gave up, and simply re-tightened the other two as much as possible. This did the trick, putting resistances down to the correct level.
If you're uneasy about removing the top plate - perhaps in case you do need to return it later and worry that they won't take it back (I doubt they can tell, but would understand any concern) - then simply loosen your three screws a little and then screw them down as hard as you can, without stripping them obviously.
I will say there's a much better than average chance this will fix it. And I am assuming the problem is similar to that we experienced in Vapor Flask clones such as the Waidea - grounding goes via that top plate to the chassis and then to the chip/board, and inadequate tightening makes this grounding poor.
