These are genuine Joyetech 510 Low Resistance Atomizers. 

Price is for one atomizer

Low resistance atomizers burn hotter than standard atomizers and therefore produce a warmer vapor, however, they may burn out or or degrade more quickly making their expected lifespan shorter than that of a standard atomizer

Useful Tip:

Refill Liquid can be dripped directly onto an atomizer. A drop or two will produce a more intense flavor and lots of vapor. However, we do not recommend directly dripping on the atomizer because it can degrade atomizer performance and shorten its life dramatically.

It is always a good idea to have a spare atomizer!

Remeber DO NOT OVERDRIP!
