Product Description

HH.357 Cisco Spec Hybrid 1.5ohm 510 Atomizer

The Original 306/510 Hybrid atomizer

Stainless | Matte Black | Cobalt Blue | Deep Red |  Dark Green

1.5ohm | 2.0ohm | 2.5ohm | 3.0ohm

These are standard 510 length and diameter

Hand assembled in the USA


These Hybrid 306/510 atomizers are the original creation of Hanna Hadawara (HH) and the first small production atomizer to be hand assembled right here in the USA. Hanna created this modification last November (2011) after his disappointment with current atomizer consistency and technology. A "how to" was posted back in March (2012) going into all the details on how you could create your own Hybrid 306/510 atomizer. The current process is a vast improvement on the original design and now with the addition of the Cisco Spec 1.5ohm 306 coils this is one remarkable atomizer. Each and every atomizer is hand assembled. The assembly process is very time consuming but the end result is an exceptionally consistent atomizer. After assembly a 50/50 blend of PG/VG is used to fire up each atomizer and adjustments are made if necessary. This meticulous testing practically eliminates the potential for DOA's and provides an extremely consistant atomizer. Each atomizer is metered before and after assembly / testing to ensure consistency.

Available in Matte Black, Stainless Steel, Cobalt Blue, Deep Red, and Dark Green all with open center posts. These will work on any device with a 510 connector including bottom feed mods.

Generally speaking 1.5ohm HH.357's would be for single 3.7v devices, 2.0ohm and above would be suitable for variable volt/watt devices, including eGo style variable volt/watt batteries ( Twist, Spinner, Revolver, etc) If you have any questions, comments or concerns regarding the performance of your HH atomizer please feel free to use our ticket system and we will respond as soon as possible.

The HH.357 is not designed to be used on any cigarette sized battery ( stick/cigalike) or any standard output eGo Style battery. Neither of these batteries have the ability to output the voltage required without over draining or causing battery stress.

Please follow this user guide carefully for optimum performance.

1. Blow excess primer out only in the direction of airflow (in through battery connector terminal and out through drip tip/mouth piece end)
    Do not rinse or clean out primer. It is needed for proper break in. Primer is 50/50 PG/VG

2. Apply enough liquid ( about 5 drops) until a slight gurgle is heard when you draw (cold draw / no power ) if no gurgle is heard add  1-2 more drops 

3. Vape some short drags to be sure there is enough liquid and to test different draw speeds. Remember the pump works on vacuum, slow / soft drags are not going to create enough vacuum.

4. If you get a bad taste on first drag, add 1-3 drops try again.

5. A bad taste or light flavor/vaper from a drag means the atomizer is ready for 2-3 more drops, depending on liquid used. 2-3 for all VG. 3-4 for VG PG.

6. Continue to vape and top off with juice until flavor starts to intensify (you will know) atomizer will "hiss" after a drag when its ready to top off, or top off when you get poor flavor.

7. When you feel you "know" your atomizer go ahead and vape hard. Please be aware when your atomier is running dry,  Enjoy!!!



A dirty atomizer can cause poor wicking and restrict the flow of liquid to the coil. Dirty wicking material will hold less juice and increase the potential for leaking.

For longer life clean your atomizers when you feel the performance drops or they are not wicking properly. High VG content, Dark jucies, and juices with high sugar content will need to be cleaned more often.

For cleaning use Ethanol/grain alcohol or vodka and let soak for an hour. Drip clean ethanol/alcohol into the atomizer from the mouth piece end and let it drip out the connector end, this would be the final "flush" before blowing the atomizer out and repeating steps 2-5.  Step 2 would require 7-9 drops after a cleaning and blow out.

Do not let the atomizer dry out after cleaning, it needs to stay lubricated. Drop the required amount of drips of your juice or straight pg/vg for pre priming immediately after blowing it out even if you wont be using for a while. Never store the atomizer dry.

Do not blow air in from the drip tip / mouth piece end, EVER. Blow air only in the direction of airflow. In through the connector end and out through drip tip/mouth piece end.

Do not dry burn for any reason, any remaining vodka inside the atomizer should burn off after the first few pulls.

Warranty Information

The HH.357 Atomizer is an experienced user product. These atomizers carry NO warranty and NO refunds. Each atomizer is metered and tested for functionality by Hanna. Atomizers are metered again before shipping, therefore NO DOA claims will not be accepted.

These atomizers are not designed to be run on standard (cigarette sized) batteries and have been known to damage or significantly reduce the lifespan of eGo style batteries.

  1. It's among the best, if not THE best, way to vape

    Posted by Jason on 13th Apr 2014

    The good:
    - Produces amazing full flavor
    - hand made to perfection
    - Easy tutorial on YouTube for setup and maintenance

    The Bad:
    - Pretty much ruins any other form of vaping; no other tank or atty I have tried compares to this.
    - Expensive (but in this case you get what you pay for)

  2. bon rendu des arômes

    Posted by on 6th Apr 2014

    Très bon rendu des arômes, j'aime beaucoup ce produit;
    Mais, je le trouve le prix cher et la livraison pour l'Europe aussi. Sinon très rapide à l'envoi.

  3. Leaky

    Posted by Drew on 16th Mar 2014

    I really wish this didn't leak so much. Man, it is great for tasting juices because you can easily blow the old juice out into a paper towel and load up a new one. But I will sometimes drop the recommended 7 drops in, and it doesn't have the gurgle, I try to take a test pull... dry. I add drops 2-3 more at a time with test pulls in between only to find out its leading out the bottom. This happens half the time, and half the time it doesn't; with the same juice mind you. Weird. It happens no matter how tightly or loosely the atty is screwed on. Maybe I will get the hang of it after a while and if I do, I will change this review to reflect my opinions after a longer period of usage. I consider myself an experienced vaper with experience with RDA's, RTA's, and RBA's etc.

    I'm new to vaping but have a lot of experience already and this atomizer provides the best flavor of all that I have tried thus far. You can REALLY taste the flavors!

  5. Best atomizer I have tried thus far

    Posted by Kurt on 27th Jan 2014

    Of course the best thing about this atty is the flavor.
    Besides that, it holds just enough juice - about 1/2ml - to suite my habbit of changing flavors fairly often.

    I have completely avoided those nasty dry hits so many have complained about, simply by operating it at about 5-6 watts instead of 10 or 12 like I see so many doing. At the lower power level, it works great, and it's easy to tell when it's running dry long before it runs out.

    Other benefits have been zero leakage, compact and light weight, and consistant smooth hits.

    Though I have several other atomizers, they tend to just sit collecting dust since I tried these.

  6. Too expensive, overhyped, but quality nonetheless

    Posted by Unknown on 19th Jan 2014

    Look, the simple truth with HH357s is this:

    1) They are WAY too expensive for what you get.

    2) They are VERY overhyped.

    3) They deliver such excellent flavor that I can't justify giving any less than 4 stars.

    The HH357 is an excellent, outstanding atty. But is it going to change your world? Probably not.

    If you can afford to use them all the time, Godspeed. But I certainly can't, and I'm afraid I will not be purchasing this product again unless the price comes down by roughly half.

    All that being said, QUALITY product, EXCELLENT flavor, GREAT atomizer.

  7. Learning curve

    Posted by Bert on 20th Dec 2013

    I found the craftsmanship to be superb. It does take a few minutes to acquaint ones self on usage.
    I found the draw to be a little tight for some reason, I am still not sure why, because there didn't appear to be a reason visible.
    I will order again if I have mastered the usage. When it is correct it is the best flavor and vapor producer. The learning curve produced several dry hits that was also the worst I have ever experienced.
    When all is correct it is near perfect.

  8. Awsome Atomizer

    Posted by Unknown on 27th Nov 2013

    Simply the best atty out there! Does not leak and gives a great hit with a great draw.

  9. great - thanks

    Posted by Unknown on 23rd Nov 2013

    great atomizer / works well.

  10. not sure what the hype is . . .

    Posted by Jon on 29th Oct 2013

    i have looked at the HH 357's for years . . . decided it must be awesome, so splurged for one . . . don't see any difference with performance vs the cisco spec 510's from this site, especially not at 3 times the cost . . . and usually my cisco spec ones last about a month . . . two weeks in and the HH 357 is dead dead dead . . .
