Tracking Speed
650 IPS
Filled only from the max tracking speed field; tracking accuracy text is not treated as IPS.
Wireless Mode
Wireless 2.4 GHz / Wired
Use 2.4 GHz/receiver or wired mode for gaming when available; use Bluetooth mainly for convenience.
Response Feel

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

Latency Notes

Do not present click latency or polling behavior as measured performance unless it has been tested directly.

Tracking Notes

sensor PixArt PAW3395 Ultra, DPI 100 – 26,000 DPI, polling Up to 8000 Hz, tracking speed 650 IPS, acceleration 50 G. Treat tracking accuracy, lift-off distance and acceleration as listed-spec information unless verified by testing.
