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. If you do not understand how to us these high performance atomizers please no not purchase them, all sales are final. 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. Super 5 Star Review

    Posted by on 16th Aug 2015

    Çok güzel ama biraz daha uzun ömürlü olmalı, yada fyatı indirilmeli

  2. Love them but not the same quality as before 2 Star Review

    Posted by on 24th Feb 2015

    I have only been using these atomizers for a full year. At first the consistency was awesome. The last order I had previous to this order, the .357's started to go down in Ohm's. I usually buy the 2.0 ohm. When I placed this past order a bit over a week ago, the .357's were running around 1.7-1.6 ohm's, but they were a bit old. The new ones I just started using for less than a week are already reading 1.7 ohms on my device. I was planning on calling customer service today, but I had this request to review the product in my inbox this morning... 2 birds one stone. When these atomizer's work correctly there is no better taste, but when the ohm's start dropping I am have to fiddle with the voltage and I can't get a consistent flavor (tastes more than bad when to "hot"). I am not into building coils or using RDA's. I loved the ease of use of the .357's, but I will probably have to start looking for something different.

  3. Just fascinated 5 Star Review

    Posted by on 9th Feb 2015

    Hi I`m Patrick from Germany,and I just wanna tell you that your atomizer is really great. After a short learning session, I´m now able to use the atty with full performance and it works unbelievable. Great taste, very clean. Now I can check how every liquid should taste and I can be sure, if the taste Bad, it is not the fault of the atty. Excuse my writing when it isn´t 100% correct.

  4. You get what you pay for 5 Star Review

    Posted by on 2nd Dec 2014

    When I first tried this atty I realized just how terrible my tired old generic lr 510 really was. Right away I could tell this atty had great flavor, tons of vapor production and plenty of throat hit. It's a fog machine even at 3.3v. Not enough to compete with one of those crazy unregulated box mods with a dual .1 ohm atty, but very good for a standard 510 size. The sweet spot is right around 3.6-4.0v from my experience so far, so it works great on a standard eGo or eGo Variable voltage battery.

  5. If I could give this six stars... 5 Star Review

    Posted by on 10th Jul 2014

    I was hesitant to drop 20+ dollars on a single atomizer. I've been having great results from the Cisco spec bridge-less 306 and for less than half the price I was content to continue using the 306. However, I started thinking what if the HH.357 is to the 306 what the 306 is to the 510's I had used before. This thought ultimately consumed me and I ordered one...

    Without delving into the realm of RBA/RDA, This is quite literally the best vape I've ever had. Nothing compares. Nothing. This is heads and tails above the rest. Any clearomizer on the market is a joke compared to a HH.357, period. I gave away my DC tanks, never to touch a Boge again. Even my tried and trusty cisco 306's were put on the backup shelf. This inside the AMP tank using a Provari 18650 is my quintessential vape experience.

    Dripping note: Before the AMP tank I dripped. This holds about 6 drops 80%VG with zero leaks out of the bottom, I never had to use a drip shield. Carried it around in my pocket without making a mess everywhere. I don't know if this is an intended design function, but it was certainly a welcome change over the bridge-less 306 I used prior.

    I will be working these into the budget from now on and I highly recommend if you can come up with the cash to give this a try. When you think about it twenty dollars isn't really that much money for a handmade boutique atomizer that delivers on every promise. Especially considering how long they last.

  6. Worth Every Penny 5 Star Review

    Posted by on 9th Jul 2014

    I've been buying these Atty's since way back when I used to get on Forums. Even with my own builds I still can't match the flavor of the 357.
    Great product at a good price, especially if you take into consideration how long they last.

  7. Another satisfied customer 5 Star Review

    Posted by on 9th Jun 2014

    Well I won't say anything you haven't heard. This thing delivers. I've been messing around with every other type of device for 9 months or so: TC Clearos, BC clearos, dual coil clearos, regular dripping atties. They all have their ups and downs. The 357, especially when combined with the Aurora BFT is the perfect solution for great flavor on the go. Fill up 2 bottles in the morning and I'm dripping all day long with no gurgling, no blowing out, no refilling, no muss, no fuss. Just squeeze and please. My only complaint is that I didn't buy one sooner!

  8. Even better than expected! 5 Star Review

    Posted by on 29th May 2014

    I love it. Great vapor production and when the flavor is gone it's really gone which helps with testing my DIY liquids. I will be getting another for general use.

  9. For Tasting Juices 5 Star Review

    Posted by on 23rd May 2014

    I got this atomizer strictly for tasting new juices. For that alone, it is already worth the price I paid!

    I will probably never be a "dripper". But for testing new juices, this thing is fantastic! I just followed the instructions about cleaning with warm tap water between juices, and it works great!!

    I get free sample juices from the company I order my juice from, and it is nice to be able to test them without devoting an entire carto/clearo to them unless I know I will like them. With the HH.357, I can test them, and then decide which ones to "pass along". (Johnny Chimpo turned out to be a keeper; Dragon Fruit and Marischino Cherry will go to friends to try out for themselves.) I "wash out" the atty between flavors, and it works as advertised.

    I did test some juices that I already know that I like, and the HH.357 didn't disappoint. Like others have mentioned, the flavors were enhanced by this atty. (Didn't really matter, because I am satisfied with those in my clearo's anyway.)

    Like I said, I am not a dripper. However, I very much appreciate the ease with which I can test out new flavors (getting the full flavor). This atomizer will be my test bed for new flavors. Who would've thought that I'd keep my sample of Johny Chimpo? Can't wait to get my next freebies..

    Which brings up another thought - when is someone going to put out a sampler pack of juices? (Like 2ml of 20 different flavors - someone's missing the boat....)

  10. It's among the best, if not THE best, way to vape 5 Star Review

    Posted by 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)

  11. bon rendu des arômes 5 Star Review

    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.

  12. Leaky 4 Star Review

    Posted by 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.

  13. FLAVORS COME ALIVE 5 Star Review

    Posted by on 31st Jan 2014

    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!

  14. Best atomizer I have tried thus far 5 Star Review

    Posted by 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.

  15. Too expensive, overhyped, but quality nonetheless 4 Star Review

    Posted by 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.

  16. Learning curve 4 Star Review

    Posted by 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.

  17. Awsome Atomizer 5 Star Review

    Posted by on 27th Nov 2013

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

  18. great - thanks 5 Star Review

    Posted by on 23rd Nov 2013

    great atomizer / works well.

  19. not sure what the hype is . . . 3 Star Review

    Posted by 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 . . .

  20. I've Been Atomized! 5 Star Review

    Posted by on 20th Oct 2013

    Better than advertised. Had it for three days only but it's performing great. Didn't know my juice tasted so good. Nicotine addicts rejoice!

  21. Buying More! 5 Star Review

    Posted by on 19th Oct 2013

    Just bought my first HH357 and wow! Through the last cheapo out and haven't tried another till HH357. Glad I bought this. I bought one just to sample juices but that has changed after i bought one! Buying a second one for bakery flavors! My other is for fruit flavors! So easy to switch out flavors to. 1.5 ohm at 4v is a beast! Even worls well at 3.7 volts.

  22. The HH.357 5 Star Review

    Posted by on 18th Oct 2013

    This still continues to be one of my favorite pre-built attys. Just consistently terrific performance in vapor, throat hit, and flavor.

  23. 6 months and counting 5 Star Review

    Posted by on 14th Oct 2013

    Ive had this thing for 6 months, and still producing great vapor. I keep expecting this thing to give out, but it keeps on trucking. If you clean the correct way, it will last a long time. I use the Provari, and this is a great combo. Recommended

  24. Great taste and vapor 5 Star Review

    Posted by on 6th Oct 2013

    Shipping to Finland took only a week.

  25. Tasty! 5 Star Review

    Posted by on 3rd Oct 2013

    The HH is putting my other devices to shame. Why am I fussing with stainless mesh and a torch just to try it and say, "Wow, almost as good as the HH.357!" Just works, thanks for the great product.
