Loading... Please wait...HH.357 Long Barrel Cisco Spec Hybrid 510 Atomizer
The Original 306/510 Hybrid atomizer
Stainless Steel | Matte Black | Cobalt Blue | Deep Green | Deep Red
1.5ohm | 2.0ohm | 2.5ohm | 3.0ohm
Hand assembled in the USA
These are longer than standard length 510 atomizers (37mm)
All stock 357's are made to VII spec.

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 after his disappointment with current atomizer consistency and technology. A "how to" was posted back in March 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. These 1.5ohm hybrid atomizers are designed for single cell 3.7 Li-ion battery mods or VV mods with outputs under 4v. DO NOT use on 5v or 6v mods or eGo/Riva batteries.
Due to the time it takes to hand assemble and test each and every atomizer and the cost of the raw materials, these HH.357 hybrids will not be offered at standard atomizer prices. We will however try our best to increase our production and efficiency and ultimately reduce the price. Available in 1.5ohm Stainless Steel all with open center posts. These will work on any device with a 510 connector including bottom feed mods.
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.
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 comsists of 50/50 PG/VG
2. Apply enough liquid ( about 5-7 drops) until a slight gurgle is heard when you take an unpowered draw on the atomizer, 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 atomizer is running dry, Enjoy!!!
CLEANING PROCEDURE:
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 will burn off after the first few pulls.
Low Resistance atomizers (atomizers below 2.0ohms) are not designed to be run on standard (cigarette sized) batteries and are known to kill or significantly reduce the lifespan of eGo | Riva style batteries. Older heavily used batteries and batteries with faulty protection circuits can be instantly rendered useless.

Coming from various $5 atomizers i was expecting big things from a $25 with shipping atomizer.
Its ok but its not this amazing piece of engineering everyone else is hyping it up to be.
They are worth about $12 each (double the cost of normal atomizers), anything more is overpriced. They really need to find a way to make these with modern manufacturing process's to bring the costs down. being hand made is unnecessary and only adds to the cost of producing them. Either that, or they are paying hanna way to much.

Like the headline says "My 1st Atty" so i have nothing to compare it to but other than the learning curve that i was well aware of it works really good and consistent once you figure it out.

I tried two of these. The first one lasted 3 days. I ordered another one as I liked the taste. It lasted 10 days. On a pro vari and always with low voltage (less than 3.7). Poor reliability. I'd recommend the standard cisco.

I have used all sorts of atomizers and none have came close to the quality of the HH357. I am sure i will be purchasing a few more!!!

After my bf purchased his and I fiddled with it I had no choice but to get my own and I LOVE IT! Best on the market PERIOD!

First off, I'm a tank person - it's just so convenient especially when chain vaping. Purchased this atty (HH357 Long Barrel 1.5 ohms) just so I can use it to try different juices. Little did I know that this little powerhouse will change the way I vape forever. Flavor and vapor I is unparalleled - except maybe for a well built dual coil in an RBA. Now I can't stop dripping - I hate it! Very consistent performance and resistance. The only thing left for it to prove is durability and longevity - let's see...
Btw, well worth the trouble purchasing this atty as they don't accept payments from the Philippines.

I ve used 510 drip short barrel atomizer before and wanted to try the HH337 long barrel. Honestly i didnt liek the draw,it was to open for me. I don't even feel the drag. If the air holes were a little bit smaller, i think it'd be a great buy but again this is a personal preference. Some may like the open draw. Its just I don't. Over all, it is ok

I've been using this for a few days now, and just used a regular 510 atty for a different flavor, I get about twice the vapor from the 357 as I do from the regular ones, if you are on the fence about getting one, just do it, you won't regret it, I'm going to order more.

Look no further. This is the best atomizer on the market. period.

I kept burning through cheap little atomizers that are constantly spitting at me and giving me burnt flavors. I decided to buy an HH.357 (2.0 Ohm long barrel) and it is hands down the best atomizer I have ever used. It has already paid for itself, with proper cleaning it should last for quite some time. I am tasting new subtle notes and flavor hints in some of my juices that weren't there before. If you are considering getting one, do it. I don't mind spending a little extra money on something that will last longer and is quality made.
