The CM Storm Sentinel Advance II is a good mouse. It does have a few quirks regarding the scroll wheel and the sensor, however, it can still compete with the other serious high end gaming mice on the market. Its shape is superb for people with slightly large hands and it can definitely give the Mionix Naos a run for its money ergonomics wise. We absolutely adore the button mechanisms used and the comfortable shape of the mouse, you can play for days without getting wrist ackes.

The build quality is sturdy and there are no oddities except for the scroll wheel. Of course the mouse is more complex than your regular Logitech mouse due to the OLED screen and the LEDs, but considering the life-span and ruggedness of both those technologies I think it is safe to say that it will last a very long time.
