Keychron continues to raise the bar with the M3 Mini – Metal Edition, a wireless gaming mouse that fuses high-end performance with sleek, ultra-premium design. Featuring a magnesium alloy body, blisteringly fast up to 4000Hz polling, and tri-mode connectivity, this compact mouse punches far above its weight class. Whether you’re deep in competitive gaming or navigating productivity tasks, the M3 Mini delivers elite-level responsiveness in a refined, minimalist shell.
Design and Build Quality
The magnesium alloy shell sets the M3 Mini – Metal Edition apart at first glance—and first touch. It offers a distinctly premium feel with enhanced durability and surprising lightness, weighing in at just around 63 grams. This combination of strength and portability is rare and makes the mouse ideal for players who want a rugged device that can handle daily use without compromise.
Its ergonomic, symmetrical shape caters well to claw and fingertip grip styles, with a compact footprint perfect for gamers with smaller hands or those who prefer lighter, more agile control. The matte finish helps reduce fingerprints and enhances grip, while the minimalist design fits seamlessly into both gaming and productivity setups.
Performance and Features
The M3 Mini – Metal Edition is built for speed and precision, backed by a suite of elite-grade specs:
-
PixArt 3395 sensor with up to 26,000 DPI
-
Polling rate up to 4000Hz (via 2.4GHz dongle)
-
Tri-mode connectivity: Wired (USB-C), 2.4GHz wireless, and Bluetooth 5.1
-
Kailh GM 8.0 switches, rated for 80 million clicks
That 4000Hz polling rate, enabled via the upgraded 2.4GHz dongle, is a game-changer for ultra-low-latency input, giving competitive FPS players the smoothest, most responsive experience currently available in wireless mice. In games like Valorant and CS2, the difference is immediately noticeable—micro-adjustments feel instantaneous, and tracking is razor-sharp.
Battery Life and Connectivity
Despite its high-performance internals, the M3 Mini offers impressive battery efficiency. The 500mAh battery delivers:
-
Up to 135 hours of use on Bluetooth
-
Approximately 70–80 hours on 2.4GHz (lower with 4000Hz enabled)
The USB-C fast charging ensures minimal downtime, and switching between devices is fast and seamless—perfect for users who bounce between gaming PCs, laptops, or tablets.
Customization and Software
Keychron’s software may be lightweight compared to other brands, but it gets the job done. It provides:
-
Button remapping
-
Polling rate adjustment (including 1000Hz, 2000Hz, and 4000Hz)
-
DPI profile tuning
-
Debounce time settings
There’s no RGB lighting, but that’s by design. The M3 Mini opts for a clean, professional look, focusing entirely on performance rather than flashy aesthetics.

Competitive gamers seeking a small, ultra-light mouse with blazing-fast response
-
Multi-device users who need Bluetooth, wireless, and wired options
