Coolermaster is one of the leaders in power supply and case manufacturing. But today we will see if they can hit a high note with their new venture the Sentinel Advance dual laser mouse. With the recession the way it is today even large companies have to create a new hustle in order to stay above water. And the new Sentinel maybe the right hustle for Coolermaster as it is large and in charge. The features are one thing but before we even plugged it into the USB port we feel in love with the size of the mouse. My narrow long finger felt right at home on the Sentinel. It was like it was an natural extension of my hand. I think this is what Coolermaster was aiming for with the Sentinel.
