FlyGuyOU Reviewed by FlyGuyOU on . Gravity Vortex? Im just curious if anyone had tried out this piece yet? It seems pretty nice but the price is a little to high and it leaks a little when tilted to push the water to the other side of the bong. From what I seen, the gravity vortex is about $90 - $100 bucks. Rating: 5
