The Corsair HARPOON RGB PRO is a good wired gaming mouse. It's lightweight but feels sturdy and has a compact, right-handed design ideal for all hand sizes using a claw grip. It's also suitable for smaller-sized hands using a palm grip and all hand sizes except for small hands using a fingertip grip. It has texturized sides, RGB lighting, and companion software compatible with Windows and macOS. Unfortunately, its cable feels cheap and isn't very flexible. Performance-wise, it has good click latency, a good lift-off distance, a broad CPI range, and a CPI you can adjust by increments of 100. However, our unit's sensor is somewhat inconsistent, tending to undershoot during quicker mouse movements.
Our Verdict
The Corsair HARPOON RGB PRO is decent for office use. It feels well-built, has a good number of programmable buttons, and software for Windows and macOS. It has a comfortable right-handed shape well-suited to nearly all hand sizes using a claw or fingertip grip and smaller hands using a palm grip. Unfortunately, it's wired-only, and the scroll wheel lacks L/R tilt functions and doesn't unlock for free scrolling.

Unfortunately, it has a stiff rubber cable, and the sensor on our unit is somewhat inconsistent, tending to undershoot quicker mouse movements.

It's ideal for a claw grip for all hand sizes, suitable for a palm grip for smaller hands, and a fingertip grip for all but small hands.

The Corsair HARPOON RGB PRO is a very good ultra-light gaming mouse, but it's on the heavier end for what we'd consider an ultra-light, and it has a stiff cable. Despite this, it has good click latency, feels very well-built, has good mouse feet that glide well on mousepads, and has a comfortable right-handed shape that's well-suited for a claw grip regardless of hand size. It's also suitable for smaller hands using a palm grip and all hand sizes except for small hands using a fingertip grip.

The Corsair HARPOON RGB PRO is inadequate for travel use as it's bulkier than most mice designed for travel and likely won't fit in most laptop cases. It's also wired-only, which might get cumbersome when using it in tight spaces like buses, trains, or planes.

Both mice are ideal for a claw grip for all hand sizes, a palm grip for smaller hands, and a fingertip grip for larger hands.
The GLORIOUS Model D is an excellent ultra-light gaming mouse, while the Corsair HARPOON RGB PRO is a great budget FPS gaming mouse. The GLORIOUS has a honeycomb body that makes it significantly lighter. It also has a much lower click latency, a more flexible cable, and feet that glide better. It's well suited for all grip types, but only for larger hands. Unfortunately, its software is only compatible with Windows. The Corsair is heavier but feels sturdier and has customization software compatible with Windows and macOS. It's best suited for a claw grip for all hand sizes.
The Corsair HARPOON RGB PRO is an updated, wired version of the Corsair HARPOON RGB Wireless. The HARPOON RGB PRO is significantly lighter, has a lower lift-off distance, a broader CPI range, a more precisely adjustable CPI, and onboard memory for settings. On the other hand, the HARPOON RGB Wireless connects via a USB receiver or Bluetooth. It has a lower click latency and a much more consistent sensor. Both mice are ideal for nearly all hand sizes with a claw or fingertip grip and smaller hands for a palm grip.
