[M] CORSAIR HARPOON RGB Wireless Gaming Mouse Review
 

CORSAIR has listened to the community and upgraded the original HARPOON RGB with wireless capabilities and a better sensor, the Pixart PMW3325. While the number of programmable buttons is the same, the DPI values can be now set up to 10000, in 100DPI increments, the Omron switch durability is now set at 50 million clicks and even if the mouse does now include a built-in lithium-polymer rechargeable battery, it only weights 99 grams without cables. As the original model, the HARPOON RGB Wireless feels best when used with a claw grip, while the rubberized side grips make sure you won’t lose precision, even during longer gaming sessions.
