A wired mouse with several useful adjustments

The Logitech G403 Hero in Black combines six programmable buttons, adjustable sensitivity, RGB lighting and a removable weight. Its appeal is not simply the sensor’s advertised maximum DPI: the more practical question is whether its controls, weight options and cable suit your gaming setup. Those features offer several ways to tailor the mouse, but they do not establish whether its shape will suit your hand.

This review is based on the supplied retailer specifications, not hands-on testing. The listing also contains conflicting sensitivity and dimension entries, so those details need qualification rather than a single confident number. The exact variant considered here is the G403 Hero RGB Gaming Mouse in Black; the color does not change its model identity.

Specifications and listing caveats

Six programmable buttons: useful flexibility, finite capacity

G HUB is the named software for configuring the six programmable buttons. For PC gaming, that gives the G403 Hero scope to bring selected actions onto the mouse rather than leaving every command on the keyboard. The important limit is that six refers to the advertised programmable-button count, not six additional side buttons. The supplied evidence does not detail the button layout.

This makes the mouse worth considering if you want a modest set of configurable inputs. If your priority is placing a large collection of game commands under your thumb, the available information does not establish that kind of arrangement. Choose by the actions you need accessible, rather than treating programmability alone as proof of suitability.

The listing also describes on-the-fly switching between five sensitivity settings. That could be useful when different games or tasks call for different cursor response, though five stages are only valuable if you can distinguish and use them consistently. Profile storage, behavior without G HUB and supported operating-system versions are not specified, so buyers planning to move between PCs should verify those points.

The sensor update matters more than the headline number

The seller advertises Hero 25K sensor capability through a free G HUB update, with a 100–25,600 DPI range. Elsewhere, the same listing describes programming five sensitivity settings within 100–16,000 DPI. The update language offers a possible explanation for the two figures, but the evidence does not explicitly reconcile them. Treat 25,600 DPI as the advertised updated capability, not a verified out-of-box setting.

For buying purposes, the distinction matters most if you expect to avoid software setup. G HUB is explicitly part of the sensor-upgrade claim as well as button and lighting configuration. The top DPI number should not decide the purchase by itself: it describes an available sensitivity setting, not proof of better aim or better control for your games.

Other sensor claims include tracking above 400 inches per second and no smoothing, filtering or acceleration. The listing also specifies a 1 ms report interval and spring-tensioned buttons. These are seller specifications and design claims, not measurements of tracking consistency, click feel or end-to-end response. They describe the intended feature set without proving how the mouse compares in actual play.

Weight tuning and cable routing on a gaming desk

The feature text gives an 87 g weight and a removable 10 g weight. This provides a concrete adjustment for buyers who want to experiment with a heavier feel without changing mice. However, the listing does not clearly explain whether its quoted 87 g includes every removable component, so a precise assembled-weight range would go beyond the evidence.

Rubber grips are another potentially useful control feature, but comfort remains personal. The seller describes a shape intended to fit the hand; that does not establish compatibility with a particular hand size or grip style. The inconsistent size fields further limit confident fit advice. Buyers sensitive to mouse height or length should confirm the dimensions before relying on this listing.

The 2.1-metre cable makes desk routing part of the decision. Consider the path from the computer to the mouse area and leave enough free cable for your normal sweep. Cable flexibility, connector type and wireless operation are not documented in the supplied facts. If your desk layout requires a specific connector or a cable-free setup, do not assume compatibility.

Surface area deserves the same attention as cable reach. Your preferred sensitivity influences how much room you may want for movement; the site’s gaming mouse pad guide is a useful next step when planning that space.

Lighting options and a concise verdict

LIGHTSYNC RGB is advertised with G HUB customization, reactions to game action, audio and screen color, and synchronization across G gear. That offers cosmetic flexibility, but the listing does not identify supported games or synchronization requirements. Treat reactive effects as a feature to check for your setup rather than a universal promise.

The G403 Hero is a plausible fit for someone seeking a wired gaming mouse with six programmable controls, sensitivity switching and removable weight tuning. Its strongest specification-based benefits are those practical adjustments. The main reservations are software-dependent customization, unresolved listing details and unknown personal fit. Confirm dimensions and software compatibility before letting the sensor ceiling or RGB features settle the decision.
