Third-party reviews

What customers like about A4Tech FB20 FB20S

  • Dual-mode connectivity (2.4GHz wireless and Bluetooth 5.0) allowing connection to up to 3 devices simultaneously
  • Silent click buttons (specifically on the FB20S model) suitable for quiet environments
  • Compact, lightweight (approx. 60g) and ergonomic design for portability and comfort
  • Long battery life with a dedicated on/off power switch to save energy
  • Adjustable DPI settings (1200, 1600, 2000) with a dedicated physical switching button
  • Support for 16 programmable gestures to perform hotkey commands

What customers don't like about A4Tech FB20 FB20S

  • Maximum DPI is limited to 2000, which may be insufficient for high-performance gaming
  • Low polling rate (125 Hz) compared to dedicated gaming mice, resulting in higher latency
  • Some users find the feet/skates to be thin and scratchy on certain surfaces
  • Lack of rechargeable battery on some variants (uses AA battery), though a Type-C rechargeable version exists in some markets
  • Small form factor may be uncomfortable for users with larger hands or those preferring a palm grip

Verdict

The A4Tech FB20 and FB20S are lightweight (60g), ambidextrous dual-mode wireless mice supporting both Bluetooth and 2.4GHz connections, allowing seamless switching between up to three devices. Key technical specifications include a 3-level adjustable resolution (1200/1600/2000 DPI), a 125 Hz polling rate, and a durable 5-million-click lifecycle powered by removable AAA batteries. Main advantages include the '16-in-One' gesture support for custom hotkey commands, an energy-saving power switch, and the 'S' variant's silent click technology for noise-free environments. However, notable drawbacks include the lack of a rechargeable battery, a relatively low maximum polling rate compared to gaming mice, and the absence of side buttons or onboard memory profiles.
