I wanted to give an update on my experience with Blu Cigs for anyone thinking of ordering. When I first received them I was annoyed because I wasn't getting much vapor from the cartridges and it was hard to get even a small hit. But I read on these forums about the liquid, and how Volcano was compatiable with Blu, so I ordered some liquid, and blank cartridges from Volcano and now I'm in heaven..... if only I could find black blank cartridges that fit on the blu batteries. Anyone know where to get them???
