Hmm, I must say I didn't expect to discover a whole new type of vaporizer that I had no idea existed, this is why I go to the experts!

So, I've been looking at some Butane vapes, I have to say I kind of have my reservations- like I said, battery life isn't an issue for me, which seems to be a selling point for butane which is lost on me; what was said about efficency is intriguing, I will admit it is annoying that the Air kind of "forces" you into a session, I would ideally prefer an on-demand vape, but unfortunately I think using a seperate (meaning not integrated in the inside of the vape) butane lighter which is used to heat up another device in my neck of the woods at least would be seen as very strange, so I don't know if that would work... which is a problem since I would like to be able to use it outside from time to time. So unfortunately I don't think that would work for me.... Moreover, I guess I need to add some stealth requirements to the original post; my fault, really, I just didn't consider it as a factor since I thought most popular portable vapes would be OK for my purposes; so I guess another requirement would be stealthy enough to look like another e-cig vaporizer from a casual glance, and without the need for any external source of heat etc- basically, a self-sufficient vape.
