It's the tank section that wobbles on the base, not at the 510. Same design as the KM3. It's barely noticeable but some people have mentioned it. I didn't even notice it until someone mentioned it.That wobble, I wonder why it's happening. Is the 510 pin too long?
The tank wobble and afc play are minimal issues and doesn't affect the vape.

So the clone makers got this one right?
