Sentinel Advance II features the same large ergonomic mouse body many have come to like, almost merging with your hand in palm grip, but packs a bunch of improvements. Thanks to its 128KB of on-board memory Sentinel Advance II, like its predecessors, lets you store several mouse profiles and their assigned macros on the mouse itself. MMO Players will be glad to hear 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 this powerful and detailed!
