better bang for your buck would be vapezilla i think... i forget the price on it... but the volcano is a bit better trust me . I went to a house with 2 volcanos and a vapezilla, 5 glass on glass bongs, and a bunch of other crazy stoner stuff. So I tried both of them out. Different days using the same amount of weed. I got higher off the volcano. When you use the volcano right you get high off it.

Volcano for the WIN!
