Hey guys, my fasttech Twist clone came in with a popped-up center pin - it springs up on one side no matter how much I try to push it back down. (This isn't the Spinner battery that's giving me so much famous trouble.) However, before I realized it was broken, it did charge for a minute, and it did fire upon pressing the button (didn't test it with a cartomizer or anything.) Would it be safe to test out this battery in comparison to my Spinner? Is there really any harm in the center pin springing up a little, especially if the carto just presses it back down? Or would this thing blow up in my face?
