I saw another thread relating an evod just spinning on the zmax and pulling the thread collar out. Everyone chalked it up to a defective device and as the guy just got his, he returned it for another one. Well, I've had my zmax for a couple months now (out of warranty) and used all numbers of stardusts and protanks with no problems, but I'm getting the same thing when I now try an evod. Does anyone know of a fix for this?
