Verdict

The A4tech FB35 and its silent-click variant, the FB35s, are ergonomic right-handed wireless mice featuring dual-mode connectivity via Bluetooth and 2.4GHz wireless, allowing simultaneous connection to up to three devices with easy switching. They offer a 3-level adjustable optical sensor (1200-1600-2000 DPI), six buttons—including two customizable thumb side buttons—and proprietary '16-in-one' gesture support for hotkey commands. Main pros include high versatility for multi-device productivity, an impressive battery life of up to 12 months on a single AA battery, and a lightweight 96g portable design. However, notable cons include a relatively low 125Hz polling rate unsuitable for high-end gaming, a lack of rechargeable internal batteries in the base models, and no support for horizontal scrolling or RGB customization.
