I just received an eGo ONE Mega V@ Atomizer from Heaven Gifts which has a loose afc ring. It moves up and down slightly, and rotates easily. I scratched the security tag to check and see if it's authentic. There are two sets of numbers, one in red XXXX XXXX, and one in black XXXX XXXX, neither set of numbers return positive. Maybe I'm not doing this correctly, which set of numbers should work?
