Verdict

The Fantech Helios II Pro S is a high-performance, ultra-lightweight (55g) symmetrical gaming mouse heavily inspired by the Zowie S2 shape. It features the top-tier PixArt PAW3395 sensor with up to 26,000 DPI, 650 IPS, and 50G acceleration, powered by a Nordic 52840 MCU that enables a true 8000Hz polling rate in wired mode and 4000Hz wirelessly via the included StrikeSpeed+ dongle. Main characteristics include tri-mode connectivity (2.4GHz, Bluetooth 5.0, and USB-C), Huano Transparent Blue Shell Pink Dot switches rated for 80 million clicks, and an improved UV matte coating for better grip. Pros include its exceptional value at under $100, its high-end components usually found in more expensive competitors, and a comprehensive accessory package featuring extra PTFE skates and grip tape. Common cons include a relatively short battery life when using high polling rates (roughly 40 hours at 4KHz) and occasional reports of inconsistent side button quality or lack of numerical battery percentage indicators in the software.
