Ubuntu 12 - Reduce Mouse Sensitivity/Input Even Further (Deceleration)

Today, I plugged in my O3 gaming mouse and noticed that it was way too sensitive to be useable. I Immediately went to the mouse sensitivity GUI and made sure sensitivity and acceleration were at a minimum, which they already were.
As always with Linux, there is a command line solution.


    Input the following command in a terminal
    xinput --list --short

    You should get a display similar to below:
    Make note of the id(s) beside your mouse. Unfortunately for me, it appears that my mouse showed up twice so I had to try the following command with both ids until it had an effect.
    xinput --set-prop (id-here) "Device Accel Constant Deceleration" (sensitivity-level)
    Please make sure to swap 'id-here' with the id of your mouse, and the '(sensitivity-level') with a number, bearing in mind the higher the number, the less sensitive the mouse will be, so 5 will move the pointer slower than 3. For my cheap Logitech b100, I found 2.5 to be the ideal number.
    That's it, the changes should be immediately noticeable, if not, try reducing the number you put in, or check your id again.
