Gaming Mouse Review
Technology
- MCU:Nordic nRF52833
All mice contain a small circuit board inside to handle the connection between inputs and the computer. Some are more complex than others, which is why these so-called Microcontroller Units (MCUs) are needed, which are essentially specialized miniature computers. Most modern mice today are equipped with more complex microcontrollers to manage things like stored profiles and CPI settings and to ensure a smooth connection, especially in wireless mice.
- Sensor:PixArt PAW3370
- Resolution:19,000CPI
The resolution of a mouse, also known as CPI, indicates how many pixels the cursor on the screen moves when you move the mouse one inch on the mousepad or table. Many mouse manufacturers and some online sources use the term DPI to refer to the same thing. However, DPI stands for ‘Dots per Inch’ and refers more to screen resolutions, while CPI stands for ‘Counts per Inch’ and directly relates to the sensitivity of a mouse. The higher the CPI of a mouse, the “finer/more precise/more frequent” the sensor can scan the surface. However, this does not mean you should play with the highest CPI.
- Polling rate:1,000 / 500 / 250 / 125Hz
The polling rate, also known as the report rate, is the frequency at which the mouse communicates with the computer and makes inputs (responds). The polling rate is measured in Hz and can vary between 125 Hz and 8,000 Hz depending on the brand and model of the mouse in question. For example, a mouse with a polling rate set to 1,000 Hz will update its position on the screen 1,000 times per second, or every 1 ms. The higher the polling rate, the more “real-time” the cursor movement you see on the screen will be.
- LOD:low, high
The Lift-Off Distance (LOD) refers to the height at which a mouse sensor stops tracking the surface it’s on. A high LOD means that the mouse continues to track even when lifted off the surface. Therefore, a low LOD allows tracking to stop sooner, preventing unwanted mouse behavior. On the other hand a higher LOD means the mouse will draw more energy which often results in a crispier feeling but for the cost of less battery life.
- Motion Sync:
Many of the latest high-end gaming mice offer the option to enable Motion Sync, which synchronizes SPI reads with USB polling, resulting in less jitter. This feature is often found in PixArt 3370 or newer sensors. Motion Sync has its pros and cons, and whether or not to use it often depends on the games you play and how much you notice these extremely fine differences.
When correctly implemented, Motion Sync promises higher sensor reactivity by synchronizing the signals the mouse sends at the exact intervals the PC is looking for these data. This leads to more consistent data exchange, which helps in tracking targets better. However, while Motion Sync is enabled and the sensor tracks more consistently, it pushes data to the next polling event, leading to a minimal higher input delay of a few milliseconds, depending on the MCU and sensor used, which polling rate is utilized, and how much power the components are allowed to draw (LP, HP, Corded / God Mode). In short, Motion Sync is comparable to VRR technologies like G-Sync, where one must decide if they are willing to sacrifice a minimal delay for a smoother experience on the monitor.
I currently recommend disabling Motion Sync
- Switches:LK Optical V2 (70M)
Under each mouse button, there is a microswitch (switch) that creates the clicking sound and sends the input signal to the computer. A microswitch consists of an outer plastic housing and a small button connected to the internal mechanism. The inside of a switch contains a spring and two metallic contact points that close upon activation to complete the circuit. Currently, two types of microswitches are used in mice – the good old mechanical switches and the newer optical switches. What makes microswitches so essential for mice is that they require very little force to activate, often just 50g. Once activated, they respond almost instantaneously.
There are many manufacturers of microswitches. The more well-known ones include Omron, Kailh, Huano, Razer, and TTC. - Switch type:optical
- Debounce:1 - 6ms
Debounce is the time a switch takes to register a keypress or mouse click. In mechanical keyboards and gaming mice, the switch can “bounce” several times when pressed, causing the device to register multiple inputs for a single press. Debounce time helps eliminate this issue by ignoring additional inputs that occur within a predetermined timeframe after the first press. However, the higher the debounce, the higher the delay of the registered “clicks.” Therefore, one aims to have as low a debounce as possible without “double clicks.”
- Click latency:3ms
Measurement values relative to the base (0ms) of the Zaunkönig Mk2 & Razer Viper 8k
Click latency is the time delay between the physical click of a mouse button and the subsequent action performed on the screen. In gaming, this delay can significantly impact the player’s performance, especially in competitive gaming. For example, in first-person shooter games, the delay between clicking the mouse button to shoot and the action executed on the screen can mean the difference between winning and losing. Several factors can influence click latency, including the hardware and software used, the type of connection, and the computer’s processing speed. Gaming mice designed for competitive gaming typically have low click latency to provide a fast and responsive gaming experience. Some gaming mice also have customizable click latency settings, allowing players to adjust the response time according to their preferences.
- Wireless:
- Battery capacity:500mAh
The capacity of the battery is indicated in mAh, which stands for milliampere-hours. It is a unit for measuring the electrical charge stored in a battery. The higher the mAh number, the more charge the battery can store, and the longer it will last.
- Battery life:64h
Important note:
The battery life always refers to the “best” mode that generally consumes the most power. This means:
- highest polling rate (e.g., 4,000 Hz)
- best wireless mode (e.g., 2.4G)
- best sensor mode (e.g., Comp-Mode on)
- RGB (on if available)
- Charging via:USB Type-C

- NVIDIA® Reflex compatible:
NVIDIA G-SYNC Displays with Reflex feature the world’s first and only System Latency Analyzer, capable of detecting clicks from Reflex-compatible mice and measuring the time it takes for the resulting pixels (muzzle flash) to change on the screen. Start every fight with the confidence and assurance that your PC is operating with the lowest possible system latency.
- Paracord:
Paracord is typically a woven or braided (not to be confused with traditional heavy braided cables) nylon cable, used in a variety of applications. Paracord became famous for its use in the military and climbing industries and is considered incredibly durable. When used in gaming mice, Paracord cables are usually lighter than traditional mouse and braided cables. The light design and flexibility allow for more freedom of movement, resulting in easier movements and quick pivots during gameplay. Besides the lower weight, Paracord also offers less “cable drag” because nylon has lower friction. Combined with a mouse bungee, the negative aspect of using a wired mouse practically disappears for most users. However, it’s noteworthy that not all wired gaming mice include a Paracord cable, and not all Paracord cables are the same. This is important to consider when purchasing a new mouse, as a wireless mouse may still be lighter or more free in movement.

Manufacturer's product description
MM712 GAMING MOUSE
FILL IN THE BLANKS
The MM712 is the next evolution of our first popular lightweight mouse, leveled up to lightweight prestige. It retains all the same benefits: gaming-grade sensor, hybrid 2.4 GHz and Bluetooth 5.1 wireless capability, PTFE feet for unrivaled glide, optical micro switches for near-instant input, and ultraweave cable for minimal snagging. However, it does all this while shedding the shredded chassis, opting instead for a seamless, hole-less profile specially engineered to remain 59g in total weight. Responsive, agile, and tactile, the MM712 truly fills in the gaps of its perforated predecessors.
FILL IN THE BLANKS
The honeycomb shell that made the MM711 such a lightweight heavyweight is now upgraded in a big way. Say goodbye to the cheese grater design: the MM712 sports a seamless whole chassis with ergonomic form factor while still maintaining a total weight of less than 59 grams. Don’t ask us how we did it — just be happy we did.
COMPETE WITH THE POWER OF THE SPEED OF LIGHT
The MM712 gives you an advantage in both durability and responsiveness with optical micro switches. These state-of-the-art babies use laser sensors to give you near-instantaneous actuation – with input that registers nearly three times faster than those from mechanical switches. In addition, the lack of moving parts means higher APMs with considerably less wear-and-tear.
AN OPTICAL UPGRADE
We don’t believe in level caps. So if we’re going to upgrade the look, we might as well upgrade the hardware too. The MM712 is outfitted with the latest pro-grade optical sensor, adjustable up to 19,000 DPI for superior responsiveness and accuracy — improved even further from our already awesome MM711.
HYBRID WIRELESS SO YOU DON’T HAVE TO CHOOSE
The MM712 is built for cord cutters and stubborn traditionalists alike. Operate the mouse in legacy wired mode, or ditch the cord for two types of wireless functionality: lag-free 2.4 GHz wireless or state-of-the-art Bluetooth 5.1 connectivity.
UNCHAIN YOUR MOUSE
When you’re mowing down infantry, you should never feel like you’re a cute widdle baby on a leash. That’s why for those traditionalists out there that ride-or-die on the cable, we’ve outfitted the MM712 with our Ultraweave Cable. Engineered in-house and composed of durable yet lightweight fiber, the cable doesn’t pull your way through the map, and doesn’t make precision aiming a pain. You might as well dump your mouse bungies now.
GLIDE LIKE A PRO SKATER WITH PTFE FEET
There’s no need to hit the black market for shady, performance enhancing gear. We’ve already outfitted your mouse right out of the box with PTFE feet, a common mod in enthusiast mice circles. We’d like to think of them more as mouse skates, providing the kind of effortless glide and premium responsiveness that you can’t find in other stock mice. And in case you’re wondering, these babies are pure, graded at more than 95% PTFE for an uncut boost to your movements.
STYLISH RGB ACCENTS FOR FORM AND FUNCTION
The MM712 comes with LEDs in our logo for a splash of personality to your game. And it’s not just for flashy good looks either – the LEDs can also serve as a handy indicator for your currently assigned DPI.
MAKE REAL-TIME ADJUSTMENTS ON-THE-FLY
Changing your real-life loadout is easier than ever thanks to our On-the-Fly system. Adjust your DPI in real time and create new keybinds and macros with the simple press of a button combo.
NVIDIA Reflex is a revolutionary suite of technologies that optimize and measure system latency to deliver the ultimate competitive advantage. Gaming mice with NVIDIA Reflex when paired with NVIDIA G-SYNC Displays provide the only system latency measurement tool that detects incoming mouse clicks and measures the time for the resulting pixels (gun muzzle flash) to change on screen. Start every match with confidence, knowing your PC is operating at the lowest possible system latency.
