The Keychron M3 Mini is a wireless gaming mouse and a smaller version of the Keychron M3. It has a symmetrical shape with textured plastic areas on both sides for added grip, and like its larger counterpart, it uses a PixArt PAW3395 sensor, one of the most accurate and consistent sensors on the market. Unlike the larger Keychron M3, this mouse uses Huano 80M switches, and while it lacks RGB lighting, it's also available for purchase with a 1000Hz or 4000Hz maximum polling rate.
Our Verdict
The Keychron M3 Mini is alright for work use. Its build quality is impressive overall. While it doesn't have many programmable buttons or a scroll wheel with free-scrolling or tilt inputs, It offers great compatibility with both Windows and macOS systems with software versions for both. It also includes both USB-C and USB-A adapter accessories to accommodate whichever ports your computer has.
- Impressive build quality overall.
- Few programmable buttons.
- Minor flexibility in the body and slightly mushy side buttons.
The Keychron M3 Mini is an excellent FPS gaming mouse. It feels sturdy and is extremely lightweight, making it easy to move quickly and accurately. It also has excellent sensor performance and very low click latency, providing a very responsive feeling experience for playing FPS games at a casual or competitive level. We bought and tested the 1000Hz polling rate variant of this mouse. Still, it's also available in a 4000Hz polling rate variant that we expect will provide marginally lower and more consistent latency performance.

Popular Mouse Comparisons
The Keychron M3 Mini is a wireless gaming mouse and a smaller version of the Keychron M3. The left- and right-click buttons use Huano 80M switches, which many people find are a bit easier to perform rapid clicks with than the Kailh 8.0 switches used in the Keychron M3. Additionally, this mouse is available for purchase with either a maximum polling rate of 1000Hz or a maximum polling rate of 4000Hz.
This mouse is positioned as a purely performance-focused alternative to its larger version. It trades the larger size and RGB lighting for a greatly reduced weight and a higher maximum polling rate option to appeal directly to a more enthusiastic market. Given its solidly budget price point, this mouse is a standout option for those looking for a small, lightweight model with wireless performance and higher polling rate options that have until now typically been reserved for higher priced flagships from other manufacturers.
