I ordered 2 of the "ego" ce4 kits from madvapes. I just got them in the mail today. One kit was for me and one kit was for a buddy. I opened my kit and filled the first ce4 hooked it up to the battery and got NOTHING. Filled the second ce4 up hooked up to battery, NOTHING. Is there something I was supposed to do first or did I just get dead ce4's? I tried them on 3 different batterys.
