I just got an EVOD today, the first one was defective and would short out, but they sent me a new one, I took it apart and rewicked and adjusted the coil and it works good now, BUT, they sent me a new one when I first told them about it (before I took it apart and fixed it). The new one though, is horrible, if I screw it all the way on, you have to draw really hard on it to get anything, now if I unscrew it a little bit, it's fine. So I don't think that it's a wicking or coil problem, I just got it today, and have used it maybe a dozen times, it just gives me a headache sitting there trying to draw on it. Any suggestions? All of the holes on the bottom are open, I compared the new one to the old one and I don't see any differences EXCEPT, the new one doesn't have EVOD BCC on the bottom, and the atomizer, the piece that goes over the coil and slides into the air tube, is about 2x's as long as the old one. I know a decent amount about the stuff but i'm lost on this. Oh, and there is NO leaking or gurgling, except for when I took off the flavor wicks to see if that would make a difference, and it didn't.... I'm using a joyetech ego.
