Hey guys I got an istick 30w a long time ago I want to put back into work but there's like a metal pice stuck on top? It has the Kanger emow mega on top I don't know how to post photos on here so this might be confusing to some. I have my battery, there's a ring above that, and an afc ring above that then where my tank screws on. I'm guessing the emow bottom is what's stuck?
