The 903 SE is the same as the 903, just a Best Buy exclusive special edition. The difference between those two and the 903 Hero is the optical sensor, the hero has the newer hero 16k sensor and the other two have the older 12k optical sensor.
Sorry, there was a problem. Please try again later.G903: common switch issues, lot's of mice have been returned for this issue. G903 HERO: has the HERO sensor, better tracking, batter battery life, 90 hours without RBG. G903 SE: G903 without the switch issue. Just erase the G903 from your mind and think of the SE as the one to replace it.
Sorry, there was a problem. Please try again later.The difference is the the dpi and the battery. Believe the dpi on the hero and g903 is 18k and the dpi on g903 se is 12k. Also battery life on hero and se are worse
