These atomizers are custom designed with a low resistance coil (1.5ohms) and create thicker and more flavorful vapor on larger e-cig batteries and mods that use single cell Lithium 3.7v batteries. These atomizers are not designed to be run on standard (cigarette sized) batteries and are known to significantly reduce the lifespan of eGo | Riva style batteries. Older heavily used batteries and batteries with faulty protection circuits can be instantly rendered useless.

 With an exposed bridge the cartridge slides over the atomizer, unlike most other atomizers that incorporate a tube.. These atomizers are for dripping and require a drip tip or juice feed system. Cartridges cannot feed liquid to the coil fast enough to function properly. There is no primer fluid used in manufacturing of these atomizers, please drip 4-5 drops of e-liquid on any new LR306, give the liquid 30 seconds or so to soak in and wet the coil. Do not run the atomizers dry as this puts excess stress on the coil and could damage the coil rendering the atomizer useless.

 There is a learning curve inherent with LR atomizers and you need to understand how to use them properly and not damage them. I don't recommend these atomizers for users who are new to vaping unless they understand the proper use. There is no warranty on these atomizers, every atomizer is metered out and is guaranteed to not be DOA.

 306 atomizers use the same thread as the 510 atomizer and will work on any E-Cig with a 510 connector.

There is no warranty on these atomizers but they are guaranteed to not be DOA.
