Fantech Helios II Pro S – Shape & Fit Overview

The Fantech Helios II Pro S is a wireless ambidextrous gaming mouse weighing 55g with dimensions of 120 × 64 × 38.3mm. Its rear-mounted hump makes it particularly well-suited for claw grip styles.

For hand sizing, the Helios II Pro S fits best for hands measuring 171218mm in length and 7591mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.

At 55g, the Helios II Pro S is classified as ultralight. Ultralight mice under 60g are a favorite for FPS players who prioritize fast flicks and reduced wrist fatigue during long sessions.

The PixArt PAW3395 sensor is a flagship-class optical sensor with flawless 1:1 tracking, zero smoothing, and zero acceleration — the gold standard for competitive play. Maximum DPI is 26,000. Polling rate: 8000Hz.
