Jeeze... This site running painfully slow for anyone else? lol took me like 10 minutes to log in and read the new replies. I just switched up to my Griff to give the smok tank a break. I noticed what looked like a piece of silicone floating in the tank was worried it was a piece of the silicone plug for single coil that melted off or something. Took it apart and it wasn't that. BUT when i took off the top to refill i noticed where it came from the damn 0-ring under the chimney. Like not the one right under the top cap, but the one under that, that is pretty hard to even see. I don't evnen know how the hell i can get to it to remove it, let alone get a new one on, it's in a weird spot. Hell, i don;'t even know which spare fits it?!?!?! do you guys know the one i'm talking about?
