Cooler Master MasterMouse MM520 & MM530 Review

Both the Cooler Master MasterMouse MM520 and the MM530 ship in essentially identical dark boxes.

Inside, a small user guide is the only extra accessory provided with each mouse.

MM520

Starting with the MM520, this is a larger mouse designed with claw grip users in mind. It is obviously an ergonomic design that excludes left-handers, though, while it weighs 132g inc. cable and 101g excl. cable.

On the left-hand side of the mouse we find two side buttons, but that is it.

On the right-hand side we find a large groove where your fourth-finger will rest, and there is a small piece of textured rubber here as well.

At the bottom of the mouse, a small LED strip is visible – this is one of the RGB lighting zones.

Back to the top of the mouse, the scroll wheel is another RGB lighting zone, and there is also a single DPI cycle button just below it.

On the underside of the MM520 we get a look at three large glide pads, as well as the optical sensor – a PMW 3360.

Lastly, the USB cable measures 1.8m and is not braided. The USB connector itself is gold-plated.

MM530

The MM530 is a completely different shape, and actually reminds me of the SteelSeries Rival 700 a fair bit. Just like the MM520, it is for right-handers only and weighs 132.5g inc. cable, and 99g excl. cable.

On the left-hand side of the MM530 we find two side buttons as well as a large piece of textured rubber – something that was missing from the MM520.

On the right-hand side of the mouse, there are no buttons but there is some more textured rubber.

The front of the mouse houses the scroll wheel, which looks the same as the MM520's wheel, though the MM530 does have two DPI buttons instead of one.

Looking to the underside of the mouse, we find two PTFE glide pads and another PMW 3360 sensor.

As with the MM520, the USB cable measures 1.8m and is not braided. The USB connector itself is gold-plated.
