⚡ Real-World Performance Analysis

Polling Rate
125 – 8000 Hz
A high polling rate helps most when your whole setup - PC, driver and game - can sustain it consistently.
DPI
10 – 30,000 DPI (42,000 OC)
Real-world aim comes down to sensor tracking and personal sensitivity, not the maximum DPI figure alone.
Tracking Speed
750 IPS
Sourced from the manufacturer's own maximum tracking speed spec.
Wireless Mode
Wireless 2.4 GHz / Wired
For gaming, the 2.4 GHz receiver or wired mode is the faster choice - Bluetooth suits everyday convenience more than competitive play.
Response Feel

Based on the listed specs, ATK U2 Ultimate should be judged by sensor consistency, click feel, weight balance and shape fit. Actual response should be confirmed through testing.

Latency Notes

Latency and polling figures are the manufacturer's published specifications, not independently measured results.

Tracking Notes

Tracking speed and acceleration figures reflect the sensor's published specifications rather than independent lab measurement.

Daily Use

For daily browsing and work, ATK U2 Ultimate can be used like a normal mouse, but its value depends most on comfort, grip fit and connection preference.

Size123.7 / 119.5 mm × 64.6 / 63 mm × 39.1 / 38.5 mm

Strong on paper

ATK U2 Ultimate can work for FPS if the shape, 39–55 g and sensor setup fit your hand. Comfort and control matter more than maximum DPI.

🧙MOBA / RPG
Good for standard use

For MOBA and RPG, the standard button layout is enough for most players. Choose a mouse with more side buttons only if you need many shortcuts.

Good
