Corsair Harpoon RGB Review

With the price of gaming hardware increasing year on year it’s getting hard to find decent peripherals at a low price. Corsair intends to fill the void for a good value gaming mouse at an entry-level price with the Harpoon RGB – A budget-friendly right-handed RGB enabled gaming mouse with premium components.

The Corsair Harpoon RGB Gaming Mouse

Weighing in at only 85 grams the Harpoon feels really light but sturdy when in hand, it’s made from high quality plastics and features a customizable RGB logo at the bottom. The mouse buttons are coupled with high performance Omron switches allowing for up to 20 million clicks on each button. The mouse has two standard left and right buttons with an adequate scroll wheel between. The scroll wheel has a satisfying feel to each rotation allowing you to feel each instance of movement, helping with weapon changes in fps games. On the left of the mouse are two back and forward buttons, which feel slightly out of place due to the high placement of the buttons. When my thumb is resting on these buttons it feels awkward due to the gap between the body of the mouse and the left mouse button.

The Harpoon is generally well shaped although its sharp angles and shortness to the mouse will make it harder to use for those who have larger hands or are accustomed to a palm grip. People with smaller hands who either use a claw or finger tip grip will feel more at home on the small chassis of the mouse. The aesthetics of the Harpoon are kept simple with a single matte black colour being implemented from top to bottom as well as textured plastic on the sides for gripping, it looks good and should work with any colour schemed build due to the RGB light at the bottom. The attached USB cable is insulated with thin plastic and does not feature any braided covering, considering this is a budget mouse it’s not expected but the inclusion would have made it feel more premium than its competition at its price point.


The 3320 Optical Sensor

There’s a major catch 22 with this mouse. Considering this is Corsair’s most entry level mouse it’s surprising to see that a “name brand” Pixart sensor has been included, it’s the type of optical sensor usually seen in more premium products, but due to the pricing of this device a low-end Pixart 3320 sensor was used, it’s accurate and feels great in most applications, but can spin out, leading to you aiming upward when you flick too fast from side to side. I’m mostly happy with Corsair’s choice in sensor on the Harpoon, but in theory it could lead to missed plays in competitive fps games, though in most scenarios it’s unlikely to happen. The DPI of the optical sensor can be adjusted in increments of 250, from as low as 250 all the way up to 6000 dpi. I was comfortable utilizing 2000 dpi when multi-tasking on my two-monitor set up and generally moved down to 1000 dpi whilst playing CS:GO and Dota 2. Mouse performance was adequate and I felt comfortable with the switch after less than a single match in each title.

Customization & RGB

Customization of the Macros, Lighting Effects as well as DPI can be adjusted using the Corsair Utility Engine – downloadable from Corsair’s website. Macros can be assigned to any of the 6 buttons on the mouse except for the Left Click. You can either assign an alternative keyboard event to a mouse button or record a set of actions and events with delays between where necessary. Lighting effects can be added and customized per profile allowing for Rainbow effects, Color Shifting, Color Pulsing and Static Colors. Each of these effects can be customized further using the “Advanced” slider at the top of the application. Further changes include being able to change the delay between specific colors or adjust the actual gradient of the color change. Pressing the DPI Toggle below the scroll wheel allows for changing of the 5 profiles of the mouse. Each with their own lighting characteristics and dpi level – these can each be adjusted in the software too. Hidden in the software is a Sniper DPI mode, which can be assigned to one of the mouse buttons via macros. This allows you to use very low dpi (default of 250) for quick changes in accuracy when sniping in an FPS game.

The Harpoon RGB Gaming Mouse is far from being the best mouse Corsair has to offer, but it presents an incredibly good value for an starter/entry level mouse. It’s comes highly recommended by us for MOBA and FPS gamers on a budget. Keep in mind however that people with larger hands may want to look at Corsair’s other offerings depending on their type of mouse grip preference.

The Corsair Harpoon RGB Gaming Mouse retails between R400 and R500 in South Africa at various retailers.
