Sensor & Performance — What the Numbers Mean

Sensor PAW3395 Ultra / PAW3950 Ultra The sensor is the heart of any mouse. Optical sensors track light reflection for precision; laser sensors work on more surfaces. For gaming, a quality optical sensor eliminates acceleration and prediction issues.
Max DPI 10 – 30,000 DPI (42,000 OC) DPI (dots per inch) controls how far the cursor moves per inch of mouse movement. Higher DPI ≠ better — most competitive gamers use 400–1600 DPI. What matters is the sensor's quality at your preferred setting.
Polling Rate 125 – 8000 Hz Polling rate is how often the mouse reports its position to your PC per second. 1000 Hz = 1ms report interval (standard for gaming). 4000–8000 Hz is available on premium gaming mice for ultra-smooth tracking.
Weight 39–55 g Heavier (100g+). More substantial in-hand feel. Some users prefer this for desk work; may cause fatigue in extended gaming sessions.

Grip Style & Hand Fit Guide

🖐️Palm Grip

Full hand rests on the mouse. Best for large hands and relaxed usage. Reduces wrist strain over long sessions.

✌️Claw Grip

Fingers arch over buttons. Good for fast, precise clicks. Favored by FPS gamers who need quick reactions.

☝️Fingertip Grip

Only fingertips touch the mouse. Maximum agility and fast movements. Preferred by competitive players.

Hand compatibility: Ultra-lightweight

Should You Buy the ATK U2 Ultimate – Specification?
