Shape

The MM720 shape is closely based on the old Spawn and Xornet shape. Highly unique and uncommon, it has garnered quite a few fans over the years. Still, people will definitely either love or hate this shape. On the MM720, it differs in two regards from most others—it's both considerably shorter and wider. The width is due to the ring finger rest on the right side, which makes it difficult to comfortably place one's pinky on that side. Whether someone will be able to get a good grip on the MM720 will greatly depend on his or her hand size and grip style. For example, with my usual claw grip, I have a very hard time using the MM720. I use my pinky to stabilize my grip, but doing so for extended periods of time is pretty much impossible on the MM720. Instead, I need to place my pinky further towards the front, which gives me less control. At the same time, palming the MM720 is perfectly possible, and surprisingly comfortable at that. Fingertip grip works just as well. The great thing about the MM720 design is that it allows for many grip styles. It's a short low-profile mouse, so there is nothing that would restrict hand placement in a significant manner. Furthermore, the big main buttons allow the M720 to be gripped more towards the front or back, depending on one's grip style and hand size.

Another peculiarity is the position of the sensor. On most mice, the horizontal position is pretty much a given, only the vertical position differs. However, things work differently on a mouse with a ring finger rest as on the MM720. In terms of sensor positioning, you could on one hand treat the mouse as though it didn't have a finger rest. On the other hand, you could simply treat the finger rest as part of the mouse and put the sensor right in the middle, between both edges. The question to ask is which is closer to the logical center of hand motion. One could argue that merely adding width by virtue of having a finger rest doesn't change where the hand sits—index and middle finger will rest on the main buttons all the same. At the same time, some people may shift their hand to the right to better accommodate the finger rest. All in all, I don't think there's a real right or wrong here. Cooler Master took the second approach, and I didn't run into any issues I would attribute to the position of the sensor.

Much like many other recent mice, the MM720 uses holes to save weight. Compared to the MM711, the honeycomb pattern is much less intrusive on the MM720. The holes are significantly smaller and only cover the back, leaving the surface your fingers touch solid. The bottom plate is perforated as well, but the two big skates and large sticker cover them entirely.


As for grip styles, I'd say the MM720 generally suits all three main grip styles (palm, claw, and finger tip grip), although the shape definitely isn't for everyone. It's a small yet wide low-profile mouse, which makes it viable for pretty much all hand sizes, depending on which grip style is chosen. For reference, my hands are 19 cm long and 10 cm wide, and I had a hard time getting a proper grip on the MM720.

Dimensions

This table includes the dimensions of the Cooler Master MM720 and several other right-handed ergonomic 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.
