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.

Popular Mouse Comparisons
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.

Test Results
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.
If you're interested in a mouse with a very similar size and shape but with an added modular system for swapping the front buttons, palm rest, and side pieces or adding your own 3D-printed parts, check out the HyperX Pulsefire Saga Pro.
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.
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.
Keychron advertises a battery life of up to 70 hours with RGB lighting off. The RGB lighting zone in the scroll wheel slowly blinks red when the battery is running low.
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.
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.

This mouse has excellent sensor latency performance, which means the sensor reacts quickly to the physical movements you make with your mouse, and they closely match the timing of your cursor movements on-screen.
The available polling rate options are 125Hz, 500Hz, and 1000Hz. You can customize up to five CPI profiles using the software. The software also allows you to adjust additional settings, including motion sync, angle snapping, and lift-off distance.
The scroll wheel has a textured rubber grip and delivers precise scrolling that's fairly quiet. The definition between steps is fairly pronounced, and the middle click button is satisfying to press without requiring too much force.
The software is well laid out and very easy to use. It allows you to change a range of expected settings, including button mapping, macros, lift-off distance, debounce delay, and RGB lighting adjustments. At the time of writing, the software is only compatible with Windows, but Keychron has stated they plan to release macOS-compatible software for this mouse in June of 2023.
