The Hercules Sr-74 is the second generation of our world’s first essential oil vaporizer cartridge that does not incorporate a heating wire, solder, glues or any silica wicks. The list of materials in the Hercules SR-74 is short and simple, it is comprised of medical grade stainless steel, Ai203 ceramic, PTFE (Teflon) and gold plated brass (electrical connections). Every single material source is hand picked so that all materials are safe and have no direct or indirect effect on the operation of the device. We designed the Hercules SR-74 essential oil cartridge knowing that our customers need a reliable and effective tool to use for their aromatherapy without interference of taste from or vapor quality from materials used in its construction. The manufacturing of the Hercules SR-74 incorporates industry first techniques and the latest machinery that makes sure it will be reliable and long lasting.
The Hercules design incorporates one true idea that we like to strive for, total user freedom. It can vaporizer essential oils, herbal loos leaf depending on the set up or both together. It is the world’s first in many aspects including the first cartridge to eliminate hybrid vapor, and first cartridge to vaporize essential oils or loose leaf. This powerful cartridge is of our own design that is not based on anything currently out there. The Hercules SR-74 heater is made from Ai203 ceramic so that it evenly heats your essential oils without burning them. It has a 1 year warranty from the date of purchase with original receipt. The 7.4v version is only available for loose leaf tobacco and essential oils.

Here's the manual
Here's the video
The persei / Hercules combo is possibly one of the most durable portable vaporizers on the market. The manual is awesome and the you tube video will fill in the gaps. Very solid construction and completely user serviceable. If you're looking for a vaporizer that doesn't use glass you won't regret this combo.

It took me a solid month to come upon the Hercules. At first I didn't know if I needed the Persei to utilize it's function, but once I talked myself into investing into a device that would last me a lifetime. The joy I've found from using the Hercules/Persei, is that it continues to provide me with clouds of vapor, and can last me weeks longer.

I've tried a few pens but this one does provide good flavorful hits. Just make sure you follow everyone's advice on how to utilize/maintain it.

I have yet to come across a better oil vape on the market today. This thing is a beast when paired with the Persei. Best vape and best company out there right now!

I did a huge amount of research before settling on the Persei/SR-74 combo. The persei arrived a week before the Hercules, so I loaded a gram of OG Kush wax I had a quarter of, into the 5.0 ohm cartridge that came with the unit. After using it for a week, I can say I was kinda unimpressed. The Persei's voltage adjustment being dependent on various batteries is a little hokey, in my opinion. Also, the flavor of the disposable cartridges wasn't great. It made the wax have a fuel taste like butane hash, and the stuff I was using was liquid oxygen purged. Enter the SR-74. I loaded a half a gram of the same wax as soon as I got this guy, and WOW! It tasted amazing from the first hit. Of course, it also gives monster hits so the wax goes fast. Now I love the Persei, because it gives plenty of power with with long battery life, and with the Hercules there is no need to change the battery configuration, as there is really no need for another cart. I would recommend this combo highly to anyone who hates taking lots of small hits to get medicated, and really just wants a portable one hit wonder. A+++

After a learning curve, it works great. Clean it on the reg. Pack it heavy at first.

Le Hercules SR74 est un vaporisateur de concentrés (et herbes) de haute qualité. Le goût est incomparable, je n'avais jamais connu une telle saveur avec un nail de quartz.
Le seul point négatif du SR74 : on a tendance à trop s'en servir !!!! :)

Over the last year or two I've been slowly gathering information on vaporizers. Having never used a vaporizer before, I was skepticle about all their promises of cloudy skies. Yet after reading and watching many reviews, I came to the conclusion that the persei/Hercules/nibbles Xl combo was for me. After receiving my sr-74, i had it up and running in no time. It produces dense, flavorful, and cool vapor and is now my number one choice when medicating. Overall it deserves 5 stars all around from form and function, to quality and precision.
Looking forward to see whats coming next from these guys!

Jamais je n'ai connu un goût aussi pur. L'usinage est parfait et le fonctionnement est au-delà de mes attentes !

I cant say more than what has already been said. The SR-71 and now the SR-74 are the pinnacle of portable oil vaping. Get through the learning curve, master the technique, and the rewards will be great. Let me be know, though, that the road to Nirvana is littered with those who didn't have the metal to master the HERCULES.
