I think the V-Tower is a ceramic heating rod, yeah? The Buddah is ceramic, made in America!, and made right in your backyard in fact in Colorado Springs by 7th Floor. The Arizer has more features, but I'd of gone with the Da Buddah personally for overall quality... $112 is a great price though, you'd have a hard time finding a buddah under $175.

Eitherway, happy vaping
