Shape

In terms of shape, the MM711 is clearly modeled after the Cooler Master MasterMouse S and retains most of its design properties. The MM711 is an ambidextrous mouse with side buttons on the left side only. It's 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 extended 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.


That having been said, the fact that the MM711 has a honeycomb shell muddles things up a bit compared to the MasterMouse S. As you can see from the pictures, only about half of the sides are covered in holes. I'm of the opinion that this a rather weird design choice. When claw gripping the MM711 (hand size: 19x10 cm), my thumb ends up sitting on the holes instead of the plain part of the left side, whereas on the right side, my ring finger sits on the plain side, while my pinky ends up on the honeycombs. These honeycombs are larger than on many other swiss-cheesed mice, so my pinky actually "locks into" one of those holes with little room to change position. Meanwhile, my thumb only occupies the cheesegrated part of the shell, so the other part being plain serves no purpose. In my opinion, a more reasonable design choice would have been to either cheesegrate the sides entirely or not at all. In the former case, you'd have the full weight savings and the same contact points for thumb and pinky as with the actual design; in the latter case, you'd have full plain sides for the best possible grip with barely any weight added compared to the current design. Of course, these considerations only apply to my particular grip, so it's perfectly possible that the design of the MM711 works better for other people and other grip styles.


Speaking of grip styles, I'd say the MM711 is first and foremost suited for claw grip, and to a lesser extent for fingertip grip. It's a small mouse with a fairly pronounced hump, so I imagine using the MM711 in palm grip to be rather uncomfortable. For reference, my hand size is 19x10 cm.

Dimensions

This table includes the dimensions of the Cooler Master MM711 and several other ambidextrous mice. "Front height" denotes the distance between the base and the 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.
