The Hammer attachment for the Persei Vaporizer is used for vaporizing herbs and essentially acts as a replacement tool for any type of lighter or heating device. Instead of inhaling butane, the user is able to vaporize without any type of foul smell or odor. The top features a 2 minute cut off timer and can reach temperatures of up to 1200F in about 45 seconds. The Hammer Rod comes with a 6 month warranty and it is not recommended that you use this top for any oil cartridges as it can and will damage your cartridges. The Hammer work best with the pass through system.
