The Corsair Harpoon RGB Pro remains a staple in the entry-level gaming market. Known for its lightweight 85g chassis and contoured shape, it caters specifically to claw and fingertip grip players who prioritize agility over a plethora of macro buttons. While it lacks the high-end sensors of its more expensive siblings, its 12,000 DPI optical sensor and Omron switches provide a reliable, no-frills experience for competitive play.

The Corsair Harpoon RGB Pro is a masterclass in functional minimalism. At first glance, it appears unassuming, but the intentionality of its design becomes clear the moment you rest your hand on it. Weighing in at a mere 85 grams, it is one of the lighter wired mice in its class, facilitating quick, effortless movements. The chassis is constructed from a matte-finish plastic that resists fingerprints remarkably well, while the sides feature a distinct triangular textured rubber grip. These grips are not merely aesthetic; they provide a secure hold during intense, sweaty gaming sessions. The shape is aggressively contoured, featuring a high hump that nestles into the arch of the hand for claw grippers, though it tapers off quickly, which may leave palm grippers feeling unsupported. The mouse feet are made of standard PTFE, providing a smooth glide on both cloth and hard pads, though they are thinner than those found on enthusiast-grade mice.

In the heat of battle, the Harpoon RGB Pro punches above its weight. Equipped with a custom PixArt PMW3327 optical sensor, it offers a maximum DPI of 12,000. While professional players rarely exceed 1,600 DPI, the headroom ensures that the sensor remains accurate and jitter-free at common gaming sensitivities. In titles like Apex Legends and Overwatch 2, the tracking feels 1:1, with no noticeable hardware acceleration or smoothing. The primary left and right buttons utilize Omron switches, providing a satisfyingly tactile and audible click that feels instantaneous. The latency is negligible thanks to the 1,000Hz polling rate. The side buttons are well-positioned for the thumb, requiring just enough force to prevent accidental clicks while remaining easy to actuate during high-action moments. The scroll wheel has distinct notches, which is excellent for weapon switching, though it lacks a "free-spin" mode found in productivity-focused mice.
