So I had an OG iStick with an ehpro kayfun v2...good set up worked well. Now the kayfun is stuck on the mod and I can't get it off. It turns slightly and makes a "click" sound then nothing. Anybody ever have this happen and fix it? I'm assuming maybe I had the airflow screw too far out and it could've dropped into the airflow grooves on top of the istick? Or maybe the threads finally just locked it up on me? I bought an new 50w istick, but I want my kayfun on it. Prob gonna just go buy a Lemo, but if I could manage to get my kayfun back I'd still like to use it in my rotation. Any thoughts?
