I haven't tried a volcano, or a mighty, but I've tried a few smaller form factor battery operated vapes, and the Magic Flight Launch Box and they never really did much for me. I liked the MLFB, but it blew through batterees and became a pain in the ass so I just stopped using it after a couple of weeks. The one vape I tried, and have stuck with daily over the last year or more, is the Dynavap M. It can get annoying to use with a torch, but it's fantastic with an induction heater, and it's perfect for people like me who can very easily get way too high. They are very expensive for what they are, IMHO, and they have a bit of a cult following, but I can't argue the fact that I use mine daily and prefer it over a bowl or a one hitter.
