The AGA Hydra- Rebuildable Atomizer In Stainless Steel
This is called Birkshire on another website, the factory name is "AGA". I picked the name "Hydra, because it performs more than one fucntion as an atomizer and plus.. it's cool)

New! an affordable STAINLESS rebuildable atomizer with a tank system holding up to 3+ml
NOTE: This is pre-assembled
 
Most rebuildable atomizers are not for beginners but if you choose to stick with the standard wick and coil setup you can simply purchase premade wick and coil.

Made with Stainless steel. Yes.. stainless steel at $25.99 (what a "steel" LOL)

Can be disassembled and put back together in minutes, very easy to clean, use and rebuild with some experience or practice.

20.4mm Overall Diameter
52mm Overall Length assembled (without drip tip)
1.0mm Airhole

Comes with
1 AGA Unit only, no drip tip.

New: Now comes with a parts kit :
(1) Wick (1) Coil - but probably enough for a few wicks
Orings (3) seals (2) Screws (1) Washer
 

Please note: due to the rebuildable nature of this item, there are no refunds and no exchanges unless there is a defective part ie, a screw is bad or something similar. Vape quality with the included wick and coil is not warrantied as it is fully customizable.

Please note very carefully that rebuildable atomizer coils and wicks have known risks.

Rebuildables are for experts, not average or beginner vapers with no multimeter or knowledge of how to use a meter, or when a meter must be used, or how electronic devices work. These materials cannot safely be used by the inexperienced or those without basic knowledge of electronics.

 This is because:

1. A rebuildable coil/wick MUST be tested carefully with a meter before it is used.
2. If it is not tested it may damage the device it is used on.
3. Faulty wicks/coils WILL blow electronic devices.
4. New coil/wick units must be tested and then used first on a strong basic electrical APV such as a Silver Bullet, that will not be destroyed by a short circuit.
5. No new coil/wick assembly should be used on an electronic device until known to be safe.
6. These items destroy electronic devices if faulty. This is a known issue.
7. These items have inherent risks and may go faulty at any time even if they were originally in good working order. The owner bears the cost of equipment damaged as a result.
8. RAs or RTAs must only be used on equipment that cannot be seriously damaged or harm the user. In practice this could mean an electrical device with a hot spring (fuse) or an electronic device that will not activate if there is a short-circuit (a dead short). Unfused devices or unprotected electronic devices will suffer damage when used with a faulty RA or RTA.
