The Performance section of this mouse is built around a fixed 1200 DPI optical sensor, with both the minimum and maximum DPI set at the same value, meaning the mouse does not support adjustable DPI settings. It operates at a polling rate of 125 Hz, which determines how frequently the device reports its position to the connected system.
The A4Tech FG15C Air2 is positioned as both a productivity and gaming mouse, connecting via 2.4GHz wireless and relying on an optical sensor for tracking. It supports gesture input, which adds an extra layer of interaction beyond standard button use, though it stores no onboard memory profiles. Power comes from a removable battery with a rated life of 8760 hours; the battery is not rechargeable, so it is intended to be replaced rather than charged in place.
The mouse features a total of 3 buttons, all of which are programmable, giving users full control over every available input. There are no side buttons, and neither a DPI switching button nor a profile switching button is included, keeping the layout minimal and straightforward.
The FG15C Air2 uses an ambidextrous orientation, making it suitable for both left- and right-handed users. It measures 109 mm in height, 64 mm in width, and 36 mm in thickness, with a total volume of 251.136 cm³, and comes in at a light 70 g. The design is kept simple — there is no RGB lighting, no tilting or thumb scroll wheel, and no extra weights included in the package.
