From What I Read I Think Your Saying Is That You Spun The Atomizer Base Off The Atomizer and Now The Broken Atom Base Is Still Attached To The Sticks Atom Connector. That was from over tightening it.......
I have used 10 different atoms, no issues.
FYI: Solder Does Not Hold The Atoms Base To The Atoms Shell, it is attached via press fit / crimp. Also Note Some of the other newer & other brand atoms are not crimped / pressed in well (u will find out if u over tighten it), so I can see this happening, but only if you overtightened it. Always screw in your atoms to make contact, your not tightening a nut & bolt here, just make a good connection. If you have strong hands or like to really tighten things be sure to lighten up, what is worse is over tightening a standard e-cig batt into its charger, that will depress the center post in causing no contact with the atom later.
Just To Clear The Air, I Say This Is Not An Actual Stick Issue, It was a user & atom issue....
