A4Tech FG10C Air / FG10CS Air

Manufacturer: A4Tech

The A4Tech FG10C Air / FG10CS Air is a wireless productivity and gaming mouse built around an ambidextrous design, making it accessible to both left- and right-handed users. It connects over a 2.4GHz wireless link and comes in at a slim 84 g with dimensions of 108 mm in height, 64 mm in width, and 35 mm in thickness — a compact, lightweight form factor suited to a wide range of hand sizes and grip styles. Gesture support is included, adding a layer of navigational flexibility to its everyday use.

On the performance side, the mouse uses an optical sensor with adjustable DPI ranging from 1000 to 2000, switchable via a dedicated DPI button. All 4 of its buttons are programmable, though there is no profile switching button on board and no onboard memory profiles are supported. The battery is removable but not rechargeable, and the rated battery life stands at 8760 hours — an exceptionally long figure for a wireless mouse of this type. RGB lighting, a tilting scroll wheel, and extra weights are all absent from the design.

Pros
  • Ambidextrous shape makes it accessible to both left- and right-handed users without compromise
  • All 4 buttons are fully programmable, giving users control over every input on the device
  • The exceptionally long rated battery life of 8760 hours means battery replacements are rarely a concern
  • Gesture support adds navigation flexibility beyond what the physical buttons alone provide
  • At 84 g with a compact form factor, the mouse is light and easy to handle across extended sessions
Cons
  • A 125 Hz polling rate is on the lower end for a mouse marketed toward gaming use, where smoother tracking is often expected
  • No side buttons limits the quick-access input options available to the user
  • The battery is not rechargeable, requiring replacement batteries rather than a simple charging routine
  • No onboard memory profiles means settings cannot be carried between different computers
  • The DPI range caps at 2000, which may not satisfy users who need finer sensitivity control at higher levels
Who is this for?

The FG10C Air / FG10CS Air is a solid fit for users who value flexibility in their setup, particularly those who are left-handed or switch between hands, thanks to its ambidextrous design. Its remarkably long rated battery life makes it well-suited to users who want a wireless mouse they can rely on for extended periods without frequently managing power, and the inclusion of gesture support adds utility for those who lean on navigation gestures in their day-to-day productivity workflows. The lightweight 84 g body and compact dimensions also make it a comfortable option for users who prefer a smaller, less imposing mouse for general desktop use.

Who is this NOT for?

Users who engage in fast-paced or competitive gaming will find the 125 Hz polling rate limiting, as it falls short of the responsiveness typically expected in demanding gaming scenarios. The absence of side buttons reduces quick-access input options, making it less practical for users who depend on thumb-accessible shortcuts in either gaming or productivity contexts. Those who need onboard memory profiles to carry their configurations between different systems will also find this mouse unsuitable, as no such storage is available on the device.

Performance:

polling rate 125 Hz
maximum DPI 2000 DPI
minimum DPI 1000 DPI
has adjustable DPI ✓

The FG10C Air / FG10CS Air operates at a polling rate of 125 Hz and supports adjustable DPI sensitivity across a range from 1000 DPI up to a maximum of 2000 DPI. This adjustable range gives users the ability to shift cursor speed to match the task at hand, whether that calls for slower, more precise movements or quicker screen traversal.

General info:

The FG10C Air / FG10CS Air is categorized as both a productivity and gaming mouse, using a 2.4GHz wireless connection and an optical sensor for tracking. It supports gesture input, adding navigational flexibility beyond standard button use. The mouse runs on a removable battery with a remarkable rated life of 8760 hours, though the battery is not rechargeable. No onboard memory profiles are available, meaning settings are not stored on the device itself.

Buttons:

number of side buttons 0
number of programmable buttons 4
has a DPI switching button ✓
has a profile switching button ✕

The FG10C Air / FG10CS Air has 4 buttons in total, all of which are programmable, allowing users to assign custom functions to every input on the mouse. None of the buttons are positioned on the side, and a dedicated DPI switching button is included for quick sensitivity adjustments. There is no profile switching button, so swapping between configuration profiles directly on the device is not possible.

The FG10C Air / FG10CS Air features an ambidextrous shape, making it equally usable for left- and right-handed users, and comes in at a lightweight 84 g with a compact footprint of 108 mm in height, 64 mm in width, and 35 mm in thickness, giving it a total volume of 241.92 cm³. The scroll wheel does not support tilting or thumb-side scrolling, and no extra weights are bundled in the package. The design skips RGB lighting entirely, resulting in a clean, understated look with no visual embellishments.

Final Verdict

The A4Tech FG10C Air / FG10CS Air presents itself as a lightweight, wireless mouse that covers both productivity and casual gaming ground without overcomplicating its feature set. Its most distinctive quality is the ambidextrous design paired with an extraordinarily long rated battery life, making it one of the more practical options for users who want a wireless mouse they can simply pick up and use without frequent battery management. The fully programmable button layout and gesture support add genuine day-to-day utility, though users with more demanding performance expectations or a need for onboard memory will find its capabilities reaching a ceiling. For anyone seeking a versatile, low-maintenance wireless mouse suited to mixed daily use, the FG10C Air delivers a focused and functional experience.
