That's the problem with BCC's, they have a nasty tendency to flood and gurgle/leak. Haven't had any such problems with my Kanger PT, but I had a big fight with my VapeOnly, ended up having to get my McGuyver on and jimmy a piece of silicone ring in underneath the head. Seems to be holding in the juice better, I think it's just a touch loose without it. But the vape is, IMO, better than the top-coils - at least, much more consistent once you get the flavor-wick/flooding issue sorted.
