The sahara vortex hookah bowl is an innovative idea on its own. Instead of leaking precious flavor down your stem, it holds in all of the shisha taste and pulls through the spire in the middle. This allows the shisha packed to smoke longer and stay moist, so it's nearly impossible to burn. Also, the design utilizes airflow to provide even and substantial heating.
I got one of these awhile back to upgrade my setup, and haven't looked back. The center support keeps foil from sinking, the extra ceramic helps distribute heat more evenly, and the draw is smooth and easy. It's also sizeable enough to have a good session sharing with others.
Just ordered the Goliath version recently too, and looking forward to testing it out! :)
