It seems to be working now. I don't have anything to test resistance on though :/
But, I can vape on it.
I had to twiddle the shell about because I couldn't vape on it, it felt blocked. Vaping easily now. There is no air hole on this thing though. Like in the video, there is an air hole by the posts (he complains about it), the baby octopus doesn't have an air hole in the base. There is one in the side of the housing though. I've taken pics as I have been going along but they have not come through to my email yet.
