Low Resistance atomizer burn hotter, produce more vapor and create a better flavor. These eGo-T Atomizers only work with eGo-T Cartridges! These are NOT recommended to be used with 'standard size' electronic cigarette and should be used on batteries with 650mAh or higher. Please make sure to keep the atomizer very wet at all times, as they do burn hotter they can burn out quicker if not taken care of. NOTE: If you purchased an eGo-T kit from us it is TYPE A. Please note that Type B Replacement Atomizers are different from Type A and can only be used with Type B Replacement Cartridges.
