Corsair has unveiled some interesting new offerings at CES, and the Harpoon RGB Wireless is definitely one of the best of those (however, I think the M65 RGB Elite is objectively a lot better even though it has a higher price). The future is steeped in wireless technology, which is confirmed day after day. When it comes to gaming mice, casual players might have been using wireless models for quite a while, but for eSports-grade competitions, they were pretty much out of the question until recently. More and more manufacturers try to catch up as Logitech is currently leading the market with their Lightspeed peripherals.

The Harpoon is rather unique in terms of shape—it's rather short, but quite bulky and has a right-handed ergonomic shell. It features grooves on the sides and the main buttons, for the sake of maximum control and comfort. It's mainly built for claw and fingertip grippers, but I'm sure it can comfortably be used in a palm grip with smaller hands.

The choice of materials is great, and the surface coatings are nice and grippy. The build quality suffers from only a minor issue, some sort of rattling that can only be heard when the mouse is shaken really hard. Other than that, it's perfect as there is no creaking, squeaking, or misalignment of any sort. As for the weight, it could be lower as at about 101 grams and with these dimensions, the mouse feels quite heavy for its size in my opinion. However, this is entirely a matter of personal preference.

Sensor-wise, the PixArt PMW3325 is not a flagship model, but it definitely isn't bad at all. It has a high, but not unreachable perfect control speed and is raw and responsive. The lift-off distance is unfortunately quite high with this sensor, but this can be helped by adding some thicker mouse feet, for instance. As for the latency, the Harpoon RGB Wireless isn't the fastest tracking device around, but the measured ~2.5 milliseconds of input lag will not be a deal breaker for most end users. I'm also pretty sure this is a firmware-related issue because it's present even when the mouse is connected via its cable, so it's not because of the wireless lag.

Buttons on the Harpoon RGB Wireless are great: they are nice and tactile and have no significant play or unnecessary travel. The main buttons have Omron switches rated for 50 million clicks, which is a great addition to the overall image. The side buttons are nice and very snappy, which is actually quite rare.

Mouse feet are the greatest letdown on this mouse in my opinion as they don't feel smooth and have quite a lot of friction. I think they should be thicker as well, with rounder contact edges to eliminate this issue. As for the cable, it's quite great; it's rather ironic that a wireless model has a more flexible cable than the company's wired models.

The Corsair iCUE software, which controls all newer Corsair products, is quite good. I didn't encounter any bugs while using it, and it's fast and does not lag. However, it does feel a tad cluttered as some settings should be more logically organized and the whole thing could be simplified a bit. Of course, there is RGB lighting on the Harpoon as well; the rear Corsair logo lights up according to the settings that are picked. The lighting looks nice, the colors are vivid, and the transitions are silky smooth.

The Corsair Harpoon RGB Wireless is truly a fantastic mouse, but suffers from a few minor errors which mainly revolve around the properties of its mouse feet. If these don't bother you and you find the shape suitable, I am happy to recommend the this mouse to you for even some higher-level multiplayer action.
