Raw Performance

The Keychron M3 is a wireless gaming mouse that keychron also advertises as being suitable for work and travel uses too. The M3 is the second mouse released by Keychron and uses a PixArt PAW3395 sensor, one of the most accurate and consistent sensors on the market. The mouse's body has a solid plastic shell and a symmetrical shape with textured plastic areas on both sides for added grip. This mouse is also noteworthy for including a range of accessories, including a charging cable, receivers, and adapters compatible with both USB-A and USB-C ports.

Our Verdict

7.2 Work

The Keychron M3 mouse is an acceptable mouse for work use. It has impressive build quality and is fully compatible with Windows and macOS systems. However, it doesn't have very many programmable buttons, and its scroll wheel lacks a free-scrolling mode and left and right tilt inputs.

  • Comfortable symmetrical shape suitable for most hand sizes.
  • Great build quality.
  • Scroll wheel lacks both tilt inputs and a free-scrolling mode.
  • Few programmable buttons.
8.4 Video Games (FPS)

The Keychron M3 is a great FPS gaming mouse. It has excellent sensor performance and click latency which provides for a snappy and responsive feeling in-game experience. It also has impressive overall build quality and a comfortable symmetrical shape suitable for most hand sizes. However, while it's somewhat lightweight, it isn't nearly as light as many FPS mice and isn't as easy to move quickly and accurately. Also, while its feet are good quality overall, they don't glide quite as smoothly as those on similarly-priced models from other companies.

  • Comfortable symmetrical shape suitable for most hand sizes.
  • Excellent click latency.
  • Great build quality.
  • Not as lightweight as many dedicated FPS mice.
  • Mouse feet don't glide as smoothly as those on many similarly-priced options.
7.5 Video Games (MMO)

The Keychron M3 is a good MMO gaming mouse, though it isn't designed for this use and has fewer side buttons than dedicated MMO gaming models. It feels sturdy and has a comfortable symmetrical shape suitable for most hand sizes. It also has excellent click latency, and its sensor is very accurate and consistent, providing smooth and responsive-feeling gameplay.

  • Comfortable symmetrical shape suitable for most hand sizes.
  • Excellent click latency.
  • Great build quality.
  • Not nearly as many side buttons as a dedicated MMO mouse.
  • Mouse feet don't glide as smoothly as those on many similarly-priced options.

Differences Between Sizes And Variants

The Keychron M3 is available in black and white color variants. We bought and tested the black color variant. You can see the label of our unit here.

Compared To Other Mice

The Keychron M3 is the second mouse released by Keychron, a company best known for producing keyboards. Unlike Keychron's first release, the Keychron M1, this model is wireless and has a solid plastic shell. This mouse also uses PixArt's PAW3395 sensor, which until now has only been included in significantly more expensive mice. Another noteworthy feature is that this mouse provides a high degree of compatibility with different kinds of computers thanks to its range of included accessories, including receivers and adapters for both USB-C and USB-A ports on your computer. This mouse delivers impressive gaming or light office work performance at a solidly mid-range price point. However, it isn't as lightweight as many similar mid-range gaming models, and its feet don't glide quite as smoothly.

For more recommendations, see our picks for the best mice, the best wireless mice, and the best wireless gaming mice.

Keychron M3 Mini

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.

Keychron M6

The Keychron M3 and the Keychron M6 are wireless mice. The M3 is designed primarily for gaming. It has a symmetrical shape, textured plastic sides, and RGB lighting. The M6 is designed for both productivity and gaming. It has an ergonomic-style right-handed shape with a thumb rest but is less accommodating to some hand sizes and grip types. It has two dedicated scroll wheels, one on the side and one on top. The top scroll wheel has L/R tilt inputs and notched and free-scrolling modes.

Keychron M1 Wireless

The Keychron M1 Wireless and the Keychron M3 are wireless gaming mice with symmetrical shapes. Both mice weigh virtually the same and deliver very similar gaming performance. The M1 Wireless has a truly ambidextrous design with two side buttons on either side. Its body also has small pill-shaped cutouts. On the other hand, the M3 only has side buttons on the left, but it has a solid plastic body and feels sturdier overall.

Razer Viper V2 Pro

The Razer Viper V2 Pro and the Keychron M3 are wireless mice with symmetrical shapes. The Razer is lighter and has significantly better gaming performance. It also has higher quality feet and longer battery life. On the other hand, the Keychron has RGB lighting, which the Razer lacks.

Keychron M1

The Keychron M1 and the Keychron M3 are mice with symmetrical shapes. The M1 is a wired-only model with small cutouts in its body to reduce its overall weight. There are two side buttons on both sides of the mouse, making it a fully ambidextrous option. On the other hand, the M3 is a wireless model with a solid plastic shell and two side buttons on the left side only. The M3 is also lighter and offers considerably better gaming performance.

GLORIOUS Model O Wireless

The GLORIOUS Model O Wireless and the Keychron M3 are wireless mice with symmetrical shapes and comparable gaming performance. The GLORIOUS is lighter and has small honeycomb-shaped cutouts in its body to reduce its weight. It also has significantly higher-quality feet that glide more smoothly. On the other hand, the Keychron has a solid plastic shell.

Logitech Signature M650

The Keychron M3 and the Logitech Signature M650 are wireless mice with symmetrical shapes. The Keychron is lighter and has much better gaming performance. It also has RGB lighting zones and an internal rechargeable battery. On the other hand, the Logitech uses an AA battery for power.

Test Results

Lighting Color RGB

This mouse has a fairly straightforward style with a matte black plastic shell and patterned plastic sides. There are RGB lighting zones in the scroll and in a strip that runs along both sides and around the bottom edge of the back of the mouse.

Receiver Storing

This mouse has sub-par portability overall. Its relatively bulky shape means you won't be able to 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

The Keychron M3 wireless mouse has great build quality overall. It feels sturdy and has textured plastic sides for added grip. However, there's a minor degree of flexibility and some creaking if you squeeze the body in certain spots. Also, you can activate the side buttons if you squeeze into the panels. These two minor issues are fairly typical with mice at this price point, and they won't impact your experience during everyday use unless you apply a considerable amount of pressure while using your mouse.

This mouse is somewhat lightweight and fairly easy to move quickly and accurately. However, it's considerably heavier than many dedicated FPS gaming mice. If you want a lighter, smaller version of this mouse, check out the Keychron M3 Mini.

Hand Size Recommendation
Palm Grip Hand Recommendation
Claw Grip Hand Recommendation
Fingertip Grip Hand Recommendation

This mouse has a comfortable symmetrical shape with a fairly tall hump towards to center of the mouse. This shape is suitable for all grip types for most hand sizes. However, if you have smaller hands, the height of the center hump will make it difficult to reach all buttons using a claw or fingertip grip.

This mouse has a very lightweight and flexible paracord-like cable that glides well across desks. Note that this mouse uses a USB-C to USB-C charging cable. That said, there's also an included USB-C to USB-A adapter if your computer doesn't have a USB-C port.

Mouse Feet
Gliding Experience
Extra Included

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 which 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 bottom of the mouse, which cycle between polling rates and CPI settings. The left button is assigned by default, but you can unlock it using the software to reprogram it. Note that you cannot assign a profile-switching function to any of the buttons, so while you can create custom profiles, you can only change between them using the software. The left- and right-click buttons use Kailh 8.0 switches. If you're interested in a similar wireless gaming mouse with a truly ambidextrous design that features a pair of buttons on both sides, check out the Keychron M1 Wireless.
