The Zeus Smite is the original Zeus vaporizer. Compact, basic, long lasting battery, top load, pretty good vapor. If your goal was an affordable basic top load portable that didn't need to be recharged often, the Smite was the one to choose.
the Zeus Arc is a huge improvement over the Smite. Ultra compact, solid design, big bowl, big vapor, haptic feedback, single button, easy to use. A higher end portable, the Arc does demand a higher price point.
The Zeus Arc GT is a Steel Arc with Gold plating. Mostly about style and having a gold vaporizer, you can also expect a slight improvement in heat distribution.
We offer all screens and parts for the Zeus vaporizers. Warranty is 2 years on the Smite and 2 Years on the Arc.
