I've been smoking volcano regularly for over a couple of months now and I can tell you that it is awesome and well worth your money. The high you get off vap bags are different from pretty much anything else you'll ever smoke out of. I love it.

A well packed vap bowl will probably go through 5-6 bags. A bag is usually enough for 4-5 people to cash. But one hit from the volcano will get you high as shit.

Also if you're into it the left over pot from a vap bowl is excellent for baking purposes. ^_^
