What customers say
The Keychron M4 Wireless Mouse generally garners a highly positive reception, particularly from a specific segment of the gaming and productivity community: those who prioritize an ultra-lightweight, compact design. Its standout feature, the incredibly low weight of just 40 grams, is frequently highlighted as a game-changer, offering an almost "invisible" feel during extended use, which is a significant advantage for fast-paced gaming or reducing wrist fatigue. Users consistently praise the precision and responsiveness of the PAW3395 sensor, noting its flawless tracking and reliability across various surfaces. The tri-mode connectivity (2.4GHz, Bluetooth, wired) is another strong point, providing excellent versatility for different setups and use cases, with the 2.4GHz wireless mode delivering a stable, low-latency experience crucial for competitive gaming. Battery life is also commonly cited as impressive, allowing for long periods of use without frequent recharging. However, the M4's compact size, while a major draw for some, is also its primary point of contention. Users with larger hands or those who prefer a palm grip often find it too small, leading to discomfort or an awkward grip. This makes it a highly specialized mouse, best suited for fingertip or claw grip users, or individuals with smaller hands. While the build quality is generally considered robust for its featherlight construction, some minor inconsistencies in button feel or shell rigidity might be mentioned, though these are not widespread issues. The accompanying software, while functional, is sometimes described as basic compared to competitors, lacking deeper customization options. Despite these minor caveats, the overwhelming sentiment is that the Keychron M4 excels at what it sets out to be: an exceptionally light, high-performance mouse for a niche but appreciative audience, delivering a premium experience for those who fit its ergonomic profile.
Know before you buy
The 8000 Hz polling rate provides extremely low latency and smoother cursor tracking, which is most beneficial for competitive gaming. For general office tasks or casual browsing, you likely won't notice a difference compared to standard polling rates.
Yes, the Keychron M4 supports multi-device connectivity. You can switch between your PC, Mac, and smartphone using the Bluetooth 5.3 connection or the included 2.4GHz wireless receiver.
The mouse is plug-and-play, so you can use it immediately without software. However, you will need the Keychron Launcher web-based tool if you want to customize button assignments, adjust DPI settings, or save profiles to the on-board memory.
You can expect up to 70 hours of battery life under typical usage conditions. Keep in mind that higher polling rates and heavy gaming sessions may reduce this duration, requiring more frequent charging via the USB cable.
The M4 features a compact, ultra-lightweight design measuring 119.9 x 65.3 x 38.9 mm. While it is highly portable and comfortable for many, those with larger hands may find it better suited for a fingertip or claw grip rather than a full palm grip.
The PixArt 3950 is a high-performance optical sensor designed for excellent tracking on most standard mouse pads and desk surfaces. However, like most optical sensors, it may struggle on clear glass or highly reflective surfaces without a mouse pad.
