Hope your problems are gone for ever.
Have you isolated anything else? ( posts, pos.deck? )
I measured my 6 decks ( FC + FT Ivogo ) and the base ( with no 510 screw inside ) - here are 2 samples

My SQR works right now, but I`m afraid to use it again. The "coating" is sh.... I`ve checked the upper edges of the post holes with a strong magnifier. The edges are very rough and some areas have no "coating". Because there is not much space between post and deck, it`s only a question of time when the positive post will get contact to the deck. If this happens while firing from a regulated mod, the mod is gone. I like the SQR, but not this one. It doesn`t make sence to save some money and kill your mods or .... . I will buy an Ematal clone version ( ehpro has one afaik ) or the original.
I will smash the decks and keep the shell for spare parts or build a lttle led inside.
FT one is already shipped back
Yes, the coating is not uniform on the decks. So the coil placement has to be exactly right or it will read like 0.1-0.5 ohms (for a 1.5 ohm coil). Its a clone I won't be using a long time I'm sure. I'm on the fence about buying an authentic. So expensive, but none of the clones are worth spit. Over the next few days I'm going to strongly evaluate whether I think its worth it. I have a feeling there won't be any better clones coming either with how quickly even the no logo ones have been pulled.
But, for the time being anyway, I'm hoping I can enjoy this one safely.

But hooray, we have our battery screwdriver/key tool
Listen, we vapers have to stick together! I say that no one should buy it because it sends the wrong message to the manufacturer. Let it is sit on the market with low sales, and then watch the price drop!
Yosen just skyped me that only the black carbon fiber and silver sleeves are ready to ship Sunday HKT, so they asked me to accept those instead because I need them ASAP for this review .. oh well, beggers can't be choosey
