The Cooler Master MM720 is an outstanding ultra-light gaming mouse. It feels fairly well-built with its honeycomb design, and it's extremely light. The right-handed design is very comfortable and works best for those using a claw grip, except for those with extra-large hands. The virgin-grade PFTE feet and the paracord-like cable help provide a smooth gliding experience on mousepads or desks. It has extremely low click latency, a high maximum polling rate, and you can reprogram most of its buttons. It also has a very wide CPI range that you can adjust in steps of 100.

The Cooler Master MM720 is slightly better than the Razer Viper Mini for ultra-light gaming. The Cooler Master is lighter, feels more comfortable for right-handed use, and has a much wider CPI range. However, the Razer is ambidextrous, has more programmable buttons, and the sensor is slightly more consistent.
The Cooler Master MM720 is better for most uses than the GLORIOUS Model O. The Cooler Master is much lighter, has a much wider CPI range, more programmable inputs, and lower click latency. However, the GLORIOUS has less CPI variation and feels better-built.

Test Results
The Cooler Master MM720 has a unique shape that's designed for those who use the claw grip. Our unit is glossy, but it's available with a matte finish as well. It has a honeycomb body to help reduce its total weight, and the holes are more subtle than Cooler Master MM710. The scroll wheel and the inside of the mouse have independent RGB zones, and the lighting inside shines through the entire body.
This mouse has decent build quality. The ABS plastic honeycomb body isn't the most solid-feeling as it squeaks and seems like it could crack if you press hard enough, but this shouldn't be an issue for everyday use. The feet feel great, and overall there aren't any loose parts that would raise any concern. If you want a honeycomb mouse with better build quality, check out the HyperX Pulsefire Haste. If you're interested in an ultra-lightweight mouse with a solid plastic body and a sturdier-feeling build quality, check out the Endgame Gear XM1r.
The Cooler Master MM720 is an extremely light mouse. It's slightly lighter than the Cooler Master MM710, but it's not as light as the Finalmouse Ultralight 2 - Cape Town or the even lighter Finalmouse Starlight-12 Phantom Small. Still, fans of ultra-light mice should appreciate it.
This mouse is very comfortable. It has a right-handed, ergonomic shape designed mainly for those who use the claw grip. The side buttons are easy-to-reach, and it comes with extra grips if you find the glossy plastic too slippery. There's a groove on the right side to rest your ring finger, but your pinky will still hang off the side.
This mouse is wired-only and can't be used wirelessly.
The cable is outstanding. It feels like a paracord and is well-made. It's light, flexible, and doesn't retain any kinks from the packaging.
The Cooler Master MM720 has outstanding feet. Despite having long sharp flat edges, the mouse glides around smoothly on a desk and even better on a mouse pad. It also comes with an extra set of feet.
The Cooler Master MM720 has a good amount of programmable buttons. You can reprogram the right click, side buttons, scroll wheel's click, and left/right inputs, as well as the CPI switch button underneath. You can access the 'Combo Mode' that gives you a second layer of programmable actions with the two side buttons and the left/right clicks when you hold down the middle button.
The Cooler Master MM720's click latency is extremely low, and you shouldn't notice any lag when gaming.
The Cooler Master MM720 comes with the same sensor as the Cooler Master MM710. It has a very wide CPI range, and its max CPI is higher than the advertised 16000 CPI. You can also adjust the CPI in steps of 100, contrary to the advertised steps of 400 CPI. You can customize the lift-off distance to 'High,' which is 2.4 mm, and 'Low,' which is what we tested at 1.2 mm. The available polling rate options are 125Hz, 250Hz, 500Hz, and 1000Hz.
The Cooler Master MM720 has a simple scroll wheel that can't be unlocked for infinite scrolling. It feels precise when scrolling, and each step is well-defined. The rubber around the wheel helps with grip.
The MasterPlus+ software offers great customization options. It's easy-to-use, and you can customize the mouse's RGB lighting or reprogram its inputs. The mouse has onboard memory, so you can use your saved settings on another computer that doesn't have the software downloaded.
