Keychron M4 Mouse

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.
