Raw Performance

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

6.6 Work

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.

Pros
  • Impressive build quality overall.
Cons
  • Few programmable buttons.
  • Minor flexibility in the body and slightly mushy side buttons.
8.8 Video Games (FPS)

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.

Pros
  • Impressive build quality overall.
  • Excellent sensor performance.
  • Extremely lightweight.
  • Excellent click latency.
Cons
  • Minor flexibility in the body and slightly mushy side buttons.
  • Mouse feet aren't as high quality as many similar models.

Differences Between Sizes And Variants

The Keychron M3 Mini is available in Black or White colorways and either a 1000Hz or a 4000Hz polling rate option. We bought and tested the 1kHz polling rate variant in the Black colorway. You can see the label for the unit we bought and tested here. There's also a larger version of this mouse that we've tested separately called the Keychron M3.

Keychron M3 Mini (4kHz polling rate) Black/White  600 mAh

Compared To Other Mice

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.

For more options, see our recommendations for the best lightweight mouse, the best wireless gaming mouse, and the best gaming mouse.

Keychron M3

The Keychron M3 and the Keychron M3 Mini are wireless gaming mice with the same shape but different sizes. The M3 is larger and has RGB lighting, which the Mini lacks. On the other hand, the Mini is significantly lighter. It's also available for purchase with a maximum polling rate of 1000Hz or with a maximum polling rate of 4000Hz, while the larger M3 is only available with a maximum polling rate of 1000Hz.

Razer Viper V2 Pro

The Razer Viper V2 Pro and the Keychron M3 Mini are wireless gaming mice that weigh virtually the same. The Razer is somewhat larger and performs better, and it has much higher-quality feet. By default, it has a maximum polling rate of 1000Hz. However, you can also buy a separate wireless Razer Hyperpolling dongle that allows a maximum polling rate of 4000Hz. On the other hand, the Keychron is available for purchase as a 1000Hz or 4000Hz variant, and it supports Bluetooth.

GLORIOUS Model O- Wireless

The Keychron M3 Mini and the GLORIOUS Model O- Wireless are wireless gaming mice with a similar size and shape. The Keychron has a solid plastic shell but is somewhat lighter. It's also available for purchase as a 1000Hz or 4000Hz variant, and it supports Bluetooth, while the GLORIOUS doesn't. On the other hand, despite being slightly heavier, the GLORIOUS has honeycomb cutouts on its palm rest. That said, it has higher-quality feet with better gliding performance and slightly lower click latency. It also has RGB lighting, which the Keychron lacks.

Razer Cobra Pro

The Razer Cobra Pro and the Keychron M3 Mini are wireless gaming mice with a fairly similar size and shape. The Razer has significantly higher-quality feet and better gaming performance. By default, it has a maximum polling rate of 1000Hz. However, you can also buy a separate wireless Razer Hyperpolling dongle that allows a maximum polling rate of 4000Hz. It also has RGB lighting, which the Keychron lacks. On the other hand, the Keychron is significantly lighter and is available for purchase as a 1000Hz or 4000Hz variant.

This mouse has middling portability. Its somewhat bulky shape means you can't slip it into most laptop cases. It also lacks compartments for storing its wireless receivers or adapter accessories, making them easier to lose if you take them on the go.

Build Quality

This mouse has impressive build quality. The body feels sturdy, and there aren't any loose or wobbling parts. The left- and right-click buttons have a satisfying tactile feel, and the sides have a textured plastic finish for added grip. Unfortunately, the side buttons feel slightly mushy, and there's some flexibility in the body's plastic panels. Furthermore, If you apply considerable pressure directly to the sides or the bottom panel, you can actuate the side buttons. That said, this is a fairly common issue with mice at this price point, and this issue isn't likely to be noticeable during normal use unless you apply a very considerable amount of pressure while using your mouse.

Fingertip Grip Hand Recommendation

This mouse has a comfortable symmetrical shape with a fairly tall hump towards to center of the mouse. The height of the hump may make it somewhat less suitable for a claw or fingertip grip, especially if you have larger hands, in which case, you may want to check out the Keychron M3 instead.

This mouse has a 600 mAh battery. On the product page for this mouse, keychron advertises a battery life of up to 70 hours with the 1kHz polling rate variant, which is the variant we bought and tested. This estimate doesn't specify, but we expect this to be the battery life using the 1000Hz polling rate and connected wirelessly via its USB receiver. There's a small LED indicator located below the scroll wheel that blinks red when the battery life is low.

While we didn't test the 4kHz polling rate variant of this mouse, the product page suggests it has the same battery size. At the time of writing, It also advertises that the 4kHz polling variant has a battery life of "up to "135 hours in 1000Hz polling rate mode." and that "Usage duration is 40 hours in 4000Hz Polling Rate mode."

While the battery duration of 40 hours using a 4000Hz polling rate seems feasible, there may be a mistake on Keychron's product page regarding the battery life of the 4kHz polling rate variant using the 1000Hz polling rate setting since 135 hours is much more likely to be the battery life estimate when connected via Bluetooth, which uses a lower polling rate of 125Hz. In actuality, we expect that the 4kHz variant will have the same ~70-hour battery life as the 1kHz variant when using a 1000Hz polling rate. If you have the 4kHz variant of this mouse and would like to share your experience of the battery life, we encourage you to reach out to us in the Discussion section below.

Overall, this mouse has good-quality feet that glide well on mouse pads and desks. However, they do feel scratchy when used directly on desks. The feet are also slightly thinner than the feet on many similar mice, and they have sharp corners that can dig into softer mousepads and create added drag.

You can program most of the buttons on this mouse except for the two buttons on the underside, which cycle CPI and polling rate settings. Note that the left-click button isn't customizable by default, but you can unlock it using the software to reprogram it. Note that while you can create custom profiles, you can't assign a dedicated profile-switching button and need to swap between profiles using the software.

Unlike the larger Keychron M3, which uses Kailh 8.0 switches, the left and right-click buttons on the Keychron M3 Mini use Huano 80M switches. These switches have a satisfying tactile feel, but many find they're able to perform faster repeated clicks compared to the Kailh switches.

All default button functions work in both Windows and macOS. The software is available for download for Windows and macOS on the manufacturer's United States-localized product page. However, at the time of writing, the Canadian product page only lists an older version of the software for Windows, which seems incompatible with this mouse. Furthermore, it erroneously mentions that the macOS version has yet to be released.
