Shape

The shape of the MM712 is no different from that of the MM710 and MM711. It is a fairly wide yet short mouse with a pronounced hump at the back that provides ample palm support. The hump isn't tapered, but rather extends across the entire width, making it quite bulky. Towards the front, it slopes down gradually. The sides have only minor curves, resulting in the width remaining fairly constant along the entire length of the mouse. The main buttons feature minor comfort grooves, and they still extend down along the sides.

Unlike on the MM710 and MM711, the sensor is positioned more towards the front on the MM712. In fact, the sensor is placed as far forward as physically possible given the limitations of the design. Compared to the more common centered position, a more forward sensor allows for a wider wrist motion arc. At the same time, those coming from a mouse with a more centered sensor may need some time to fully adjust.


As for grip styles, I'd say the MM712 mostly suits claw grip. It is a small mouse with a fairly pronounced hump, which should make it generally suit medium-sized and smaller hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the MM712 very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Cooler Master MM712 and several other ambidextrous mice. "Front height" denotes the distance between the base and main buttons. Measurements with two decimals have been taken with a caliper, while those with one decimal have been taken with a ruler. For a full list of all measurements taken, please refer to this sheet compiled by an esteemed community member.
