Set DPI and polling rates that match your screen, desk space, and aim style - prioritizing eDPI and consistency over marketing numbers. Get clear thresholds (400–1600 DPI, 500–1000 Hz, 3200 DPI ceiling) and a quick tuning plan to improve control without overspending.

Prioritize shape over specs: match a mouse’s hump height, width, and taper to your hand geometry to stabilize aim and reduce latency. Use measurement formulas and a step-by-step testing protocol to find a palm-grip fit that lowers fatigue and improves flick consistency.

Evidence-backed testing finds only seven of 11 buttons are reliably reachable, while early wear, CPI instability, and shaky software raise the real cost of ownership. Get practical buy/skip guidance and sturdier alternatives for players who prioritize consistency and durability.

Clean and protect the sensor in under 8 minutes with a no-disassembly, solvent-free method that targets the real cause of drift and jitter. Diagnose issues, clean safely, and validate with simple tracking tests to restore precise aim and reduce strain over long sessions.
