ASUS Logitech G403 HERO Gaming Mouse 25K Sensor 87g 10g Weight 16 Buttons Black

Right-handed optical gaming mouse

The ASUS Logitech G403 HERO is a right-handed optical gaming mouse built around a HERO 25K sensor that delivers 1:1 tracking, 400-plus IPS and a 100 to 25,600 DPI range with zero smoothing, filtering or acceleration. It connects via 2.4 GHz wireless or wired USB and includes a 2.1-metre braided cable. LIGHTSYNC RGB provides 16.8-million-colour lighting that reacts to in-game action, audio and screen colour. The shell weighs 87 grams and a 10-gram optional weight lets you adjust the balance.

Suits competitive players who want adjustable

The shape, rubber side grips and removable 10-gram weight suit competitive players who want to fine-tune mass and balance for fast aiming. Six programmable buttons and on-the-fly DPI shifting across five presets support MOBA and FPS keybinds. Left-handed users should look elsewhere because the ergonomic contour is moulded for right-hand grip only. Buyers who want more than 16 programmable buttons or a fully ambidextrous shape should consider other form factors.

HERO 25K sensor with 25,600 max DPI

The single specification that decides fit is the HERO 25K sensor’s 25,600 maximum DPI combined with 400-plus IPS tracking speed and a 1-ms report rate. This ceiling covers pixel-precise sniping and high-speed swipes without smoothing or acceleration. If your workflow never exceeds 16,000 DPI or you prefer a heavier, fixed-weight mouse, the sensor headroom and removable weight will not be decisive factors.
