  1. Very satisfied, worth every penny!

    Posted by Justin on 25th Jul 2014

    The hercules sr74 is amazing, super smooth and a great taste. It takes a couple puffs to figure out the best way to hit it for your liking, you can get from medium to extremely large amounts of vapor. Once you do it a time or 2 assembly is pretty simple. I gave 4 stars for one reason, it isn't very economical. This thing craves oil and will go through it very fast. For me the 3.7v black rod makes it 5+ stars.

  2. Durable completely user serviceable

    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.

  3. Hands down the best.

    Posted by Jarrod Scott on 9th May 2014

    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.

  4. Best taste

    Posted by Unknown on 27th Apr 2014

    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.

  5. Best portable oil vape on the market

    Posted by Unknown on 13th Mar 2014

    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!

  6. JUST BUY IT!!!

    Posted by Cohesive1 on 12th Mar 2014

    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+++

  7. It works great

    Posted by Reseda Mike on 3rd Mar 2014

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

  8. Fantastique !

    Posted by VapVap on 22nd Feb 2014

    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 !!!! :)

  9. No disappointment at all!!!

    Posted by Esb on 20th Feb 2014

    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!

  10. Fantastique !

    Posted by VapVap on 16th Feb 2014

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