Hi, A buddy at work is selling his Nemesis and im not sure if it the Genuine article or a Clone. He wants $40 for it. Comes with a IMR 18650 1600 mah battery, Charger (3.0 or 3.6 volt switch) Not sure if its the right charger, And a SmokTech Dripper RDA. If its the Clone he wants too much. If its Genuine I'm stealing it. So, How do i tell the difference? Thanks.
