The Keychron M1 is a lightweight, wired mouse with rounded, pill-shaped cutouts in the top, sides, and bottom of its outer shell to reduce its overall weight. It has an ambidextrous shape and has a pair of side buttons on either side. It feels well-built overall and is well-suited for most hand-sizes; however, it isn't suitable for small hand sizes using any grip type. Performance-wise, it has low click latency, a very low minimum lift-off distance, and you can adjust the CPI by increments of 100 within a very wide range. Also, all of its default button functions work in Windows or macOS.
Our Verdict
The Keychron M1 mouse is adequate for office and multimedia work. It feels well-built and has a comfortable, ambidextrous shape suitable for most hand sizes. You can also program most of its buttons using the companion software. Unfortunately, there aren't any wireless connectivity options, and the scroll wheel lacks L/R tilt buttons and doesn't unlock for free-scrolling.

The Keychron M1 mouse is great for FPS gaming. It's lightweight, feels well-built, and has an ambidextrous shape suitable for most hand sizes; however, it isn't suitable for small hands using any grip type.

Performance-wise, it has low click latency, a very low lift-off distance, and a broad CPI range. Unfortunately, you can only adjust the CPI by increments of 100, which isn't as precise as some gamers may prefer.

The Keychron M1 mouse is inadequate for travel and isn't designed for this use. It's bulky and may not fit in most laptop cases, and it lacks wireless connectivity options, meaning it can be cumbersome to use in small spaces like buses, trains, or planes. That said, it feels well-built overall and has a comfortable, ambidextrous shape suitable for most hand sizes. It also has onboard storage, meaning you can use custom settings on computers without the software installed.

Test Results
The Keychron M1 mouse has a matte black plastic body with pill-shaped cutouts on all surfaces except for the front of the left and right-click buttons and spaces on either side below the side buttons. Its shape is very similar to many other ultra-lightweight mice, notably the GLORIOUS Model O. There is RGB lighting which includes an LED-lit scroll wheel and an LED strip along either side of the mouse. You can adjust these RGB elements using the customization software, but you can only adjust them as a whole, not independently.
The Keychron M1 mouse has good overall build quality. However, there's slight flex in the palm area and the bottom if you apply enough pressure. There's also a slight rattling sound if you shake the mouse. Unfortunately, you can also actuate any of the side buttons by squeezing the plastic surfaces near them with enough force. That said, none of these issues should present any problems when using the mouse as intended.
