Broke my RooR last night and went bong shopping today and bought one of these mother fuckers. If your REALLY careful they dont leak any water at all and it is the most economic way to smoke. I usually smoke 4 grams a day and with the Vortex i probably smoke 2.5 and get the same effects. Pays for itself if your a heavy smoker. itll pay itself off for me in about 4 weeks.
