NM. I got it sorted. I took that silicone bit out with a toothpick. Washed it out real good. I love this thing! Most helpful post I've read on this board. Thanks!
Greetings; I got an eGo-CC 6 weeks ago (a real Joyetech CC) and, as I've mentioned in a couple other threads, I've had a terrible time with mine. As PO describes, refilling it by removing the silicone cap was the only reliable method I could find.
When I put a needle-tip bottle in that centre hole (in the silicon cap), it was like the tank would become airlocked, and I couldn't get e-liquid into the tank no matter how hard I squeezed the bottle. At a certain point, the liquid would just gush out over the the cap, and into those air slot on the side of the tank, and then spill out the mouthpiece.
I believe I got a defective CC, because it also leaked like a sieve during vaping, though I've had no success in terms of getting the vendor or the mfc to allow me to return it. I eventually gave up, and got another BCC clearo, a Davide (Mini), which has been fantastic. The same (if not not better) fantastic vapour taste and quantity as the CC, but zero leakage - literally not one drop since I started using the Davide.
