Design and Build Quality
The R3 weighs just 46g thanks to its magnesium alloy construction — the same material used in premium mice costing three times as much. The hollowed-out design reduces weight while improving airflow, keeping your grip cool during intense sessions. The build feels solid with zero flex or wobble. Buttons don’t rattle, the scroll wheel has satisfying tactile feedback, and the matte finish resists fingerprints well.
The shape works for both right and left-handed users with palm and claw grip. Weight distribution is well-balanced, making extended gaming sessions comfortable without fatigue.
Performance and Sensor
The PAW3395 is the same sensor found in flagship mice from Razer and Logitech. Tracking is flawless — accurate, smooth, and free of acceleration issues. Combined with Kailh GM 8.0 switches rated for 80 million clicks, every input feels crisp and reliable.
The 8KHz Polling Rate — Does It Matter?
Standard gaming mice run at 1000Hz. The R3 runs at 8000Hz in wireless mode, reporting position to your computer 8 times faster than standard mice.
For casual gamers, 1000Hz is fine. But if you play competitive FPS at 240fps+, 8KHz reduces micro-stuttering noticeably. Pro players in Valorant and CS2 have started adopting high polling rate mice for exactly this reason. At this price, it’s a real advantage that’s hard to find elsewhere.
Connectivity and Latency
The R3 supports tri-mode connectivity — 2.4GHz wireless, Bluetooth, and wired USB. The 2.4GHz connection is rock solid with no perceptible latency. Bluetooth drops polling rate to 1000Hz but is useful for switching to a laptop. Wired mode gives zero latency and continuous power without needing to recharge.
The 10-meter wireless range ensures smooth performance without signal drops.
Battery Life
The R3 offers several days of gaming on a single charge. With 8KHz enabled expect 40–50 hours per charge. Switching to 1000Hz extends this significantly. USB-C charging takes about 1.5 hours, and you can use the mouse while charging — zero downtime.
