This is a genuine Joyetech Low resistance Type A eGo-T 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.

Compatible with any eGo/eGo-T or eGo-C battery, but only Compatible with Type A eGo-T Cartridges (5 Pack)

Type A Cartridges only work with eGo-T Type A Atomizers which are cone shaped (tapered or smaller at one end than the other)

Type B Cartridges only work with eGo-T Type B Atomizers which are cylinder shaped (straight walls that create the same sized opening at both ends)
