Yeah, my full black from January is also working fine. But I still like the idea of a floating 510.Sooo Rossum; what are your thoughts on this? My full black XPV from Jan '14 is working fine with the original 510 but a floating pin option is sure to allow all atties moving forward to work?
Good question; I suppose that depends on how much current you're pushing through it.What do you think the voltage drop is regarding a fixed center pin vs. a floating one?
I have not tried to adjust mine.I had read somewhere that the center pin in the KFL could be sheared if one wasn't careful?
I just saw the connector on fatdaddyvapes site and it looks like it comes with the 22mm base which looks like it will go over the edges of the XPV or at least set over top of the four screws??
At least every topper would look and set flush mount on the device?? I wonder how much they will charge for this upgrade,if it's in the $15 range it will be worth every penny.
Here is a preview of the new connector in a testbed installation. As you can see it is a stainless, low-profile main body, and it uses a brass spring-loaded center pin. In our testing all of our atomizers connected and fired with no adjustment needed. This connector is a collaboration with another well-known or soon to be well-known producer, and is exclusive to Protovapor.

Even if it sets flush we still have the four screws that still protrude above the flush top cap??

What was your order number?
My KFL+ doesn't fire on it but my Russian 91% did, so I didn't lose any sleep over it... the KFL+ fires on the Provari just fine and I never bothered to try adjusting the center pin in the KFL. I had read somewhere that the center pin in the KFL could be sheared if one wasn't careful?
