Longer notes from the same comments we summarized above.
What people reported
Owners often praise the Keychron M3 for its value for money, especially considering its versatile connectivity options including wired, 2.4GHz dongle, and Bluetooth. Many appreciate its suitability for seamless switching between Windows, Mac OS, and iPad. The mouse is noted for its programmable buttons and a weight of around 79 grams.
Problems people mention
A recurring concern involves connectivity reliability. Some users experienced issues with the USB cable breaking quickly, the 4K dongle not being recognized, or the mouse losing connection via the dongle entirely. When using the 4K Hz polling rate, some reported experiencing lags and momentary stops. Finding the Keychron Engine software for customization (RGB, DPI) was also a challenge for some, with the software noted as Windows-only for now. One owner specifically mentioned an issue with the "gripped" side of the mouse.
Where owners disagree
There's some confusion regarding the advertised battery life and capacity, with different figures appearing for 1K and 4K polling rates on the M3 and M3 4K versions. While some find its performance suitable for casual use, others suggest it's not ideal for competitive FPS games, recommending other mice in the $80 range for that purpose.
Who it's for
The Keychron M3 appears to be a good fit for users seeking a budget-friendly wireless mouse with extensive connectivity options for multi-device use (Windows, Mac, iPad). It suits those who appreciate programmable buttons and a medium weight for general productivity and casual gaming. Buyers should be aware of potential connectivity issues and software limitations, especially if 4K Hz polling for competitive gaming is a priority.
