CM Storm Sentinel Advance II 8200DPI Gaming Mice features the large ergonomic mouse body which many have come to adore. It almost merges with your hand in your palm grip. The gaming mouse is lightweight, ergonomically designed and forged with a reassuringly solid design. Thanks to its 128KB on-board memory, Sentinel Advance II lets you store several mouse profiles and their assigned macros on the mouse itself. MMO Players will be glad to hear that the Sentinel Advance II supports CM Storm TactiX, assigning functions to combinations of mouse buttons and the mouse wheel. As a result a vast amount of commands and macros can be programmed to its 8 buttons. Sentinels Advanced Driver Panel lets you create detailed Macros and Scripts, including commands to move the mouse pointer to predefined coordinates on your Display. No other Mouse on the market supports Macros so powerfully and in such a detailed manner!
