The Sentinel has 5 customisable profiles, which can be scrolled through using a button on the mouse. Each profile can have a certain lighting colour assigned to it, or you can have all the profiles stick to one colour. Here are the mouse's 5 default colours:

 

  

  

 

The OLED screen is used for a number of purposes. When switching through profiles it tells you which profile is active , the current X and Y direction sensitivities and also displays a small logo of your choice. The default logo is the CM Storm logo, but with the aid of the software, you can upload your own to the mouse.

 

  

 

Putting the bundled CD into your drive brings up a small menu with the choice of either installing the driver/software or running it off the disc. Once you have the software loaded up, you are greeted with the screen below. On the right we have sliders for adjusting the DPI levels, sensitivity, double click speed and button response. Down the bottom we have the ability to change the mouse's polling rate, and on the left we can assign different commands to each button. The degree to which you can adjust the settings on the mouse absolutely blew me away, I've never seen so many sliders and option boxes.

 

 

The colour control screen is pretty nifty, and allows you to change all the lighting settings. There is 8 colours to chose from, and the top/front can be coloured differently. You can also change when the lights come on, with the nifty option to make the lights 'breathe'. This screen also has the option to upload your clan logo, which would then be displayed on the OLED screen... Sweet.

 

 

The last screen worthy of note is the macro's screen. This lets you record key/mouse movements and then assign them to a button on the mouse, which could potentially be a massive time saver. Again, the options available here are absolutely insane, only a truly dedicated gamer would manage to use them all at once. You can view saved scripts and macro's from the library tab.
