The Mouse
The mouse that Cooler Master is shipping with the MasterSet MS120 is a claw-grip style mouse. It is all black and sort of has a plastic feel to most of it.
The mouse features two main buttons, which are powered by OMRON switches. In the center you have a scroll wheel, which has a rubber coating on it for a comfortable grip. Below the scroll wheel is a DPI switch button that will cycle through the 4 different DPI levels (500, 750, 1500, 3500) as well as switch the colors of the LEDs on the mouse.
On the left side of the mouse you have two more buttons that can function as back or forward when web browsing or a quick weapon switch when gaming. On the opposite side there are no buttons, but a rubberized section to give you a better grip.
Flipping the mouse over we have three large mouse feet and at the center is the PixArt optical sensor.
Cooler Master let us know that in select regions they will also offer a MasterSet MS121 which comes with an ambidextrous mouse which you can see pictured below.
