So I recently just bought this for the temperature control, however none of my kanger tanks seem to fit flush on the device. Even taking off the beauty ring does nothing. I researched some and saw others talking about a 510 connector adjustment?
Is this possible or is anyone else having the same issue? Its a stainless silver connector with only one air way on the connector.
