If you\u2019re looking for the best gaming mouse that performs well, and still affordable, then the Corsair Harpoon RGB Mouse is exactly that. Instead of being tethered to a wire, the Harpoon RGB sports a wireless connection via Bluetooth, and still manages to have a fast connection speed. It\u2019s by far one of the best options out there for a budget mouse. If you need a keyboard too, take a look at our Logitech MX500 review for a combo.\r\n\r\nWhy We Like It - Corsair Harpoon RGB Mouse\r\nThe Corsair Harpoon RGB Mouse brings performance and accuracy to gamers without the need of a wire, and its comfortable design makes it possible to enjoy that performance for hours to come.\r\n\r\nPerformance\r\nEven as a wireless gaming mouse, the Corsair Harpoon RGB Mouse is no pushover in terms of performance. With a DPI of 10,000\u2014much higher than the Pictek Gaming Mouse\u2014it can accommodate a wide range of sensitivities. Furthermore, its IPS handles fast movement really well, not to mention a sub-1ms connection speed. You won\u2019t even notice any lag input. However the IPS is much better on the Razer Lancehead Tournament Edition.\r\n\r\nThe battery life on the Corsair Harpoon RGB is impeccable, providing up to 60 hours of great performance before it needs to be charged with its USB cable. But if wireless isn\u2019t your thing, you can keep it plugged in. It\u2019ll work just as well, if not better when plugged in.\r\nDesign\r\nThe Corsair Harpoon RGB Wireless Mouse has an ergonomic design; smooth curves reduce fatigue when the mouse is in use whether you use palm or claw grip. The soft rubber side grips provide a nice grippy surface that prevents finger slippage, which is where you\u2019ll find two additional side buttons. The mouse buttons, and the rest of the mouse, even have a somewhat textured surface rather than smooth, unlike other gaming mice. RGB lighting shines through the Corsair logo, which can be changed using iCUE software, including its six programmable buttons. DPI settings can be altered using the button near the scroll wheel.\r\nValue\r\nConsidering the Harpoon RGB gaming mouse performs really well for its low price, build quality, and really long battery life, you are getting a fantastic deal here. This is especially true when you put it to the test. After hours of playing in one day, it\u2019ll still perform just as well, handling most of what you throw at it before it needs to be charged. And with how comfortable it is, you won\u2019t feel the fatigue.\r\nCorsair Harpoon RGB Mouse Wrap Up\r\nThis Corsair Harpoon RGB Mouse review ultimately shows that the wireless mice have come a long way, and definitely ready to be used in a serious manner. Its DPI optical sensor and fast reacting IPS make it a serious contender as your next gaming mouse. You might come across Bluetooth input lag, and its design is limited to righties like the Logitech G203 Prodigy, the Corsair Harpoon\u2019s performance more than makes up for it.
