The 2.4GHz connection feature Corsair’s Slipstream Wireless technology that boasts a latency of less than 1ms. The former requires a USB dongle, which can be conveniently stowed in small compartment on the bottom the mouse so you don’t lose it. The mouse features not one but two wireless modes, and a small switch on the bottom lets you choose which one you’d like to use: 2.4GHz wireless or Bluetooth. Not to mention the fact that your palm covers it anyway. Then again, if you plan to use the mouse in wireless mode primarily, you may want to disable the RGB lighting to extend battery life. Most of the patterns for the Corsair logo are indistinguishable from one another because they don’t cycle through multiple zones but simply blink in the single zone – a somewhat underwhelming RGB lighting display. It’s true that you can program only the Corsair logo on the palm rest with a color-changing pattern, but you can also program the colors of the LED indicator light for the five DPI settings on the mouse, along with the separate sniper DPI setting. The Harpoon RGB Wireless bills itself as having a single zone of RGB lighting, but there are two if you count the LED on the DPI button. The mouse lacks a dedicated sniper button, but you can reprogram one of the side buttons to act as such. The side buttons are perfectly located just above where your thumb rests they are easily accessible but kept out of your way when not needed. On top, there’s the right- and left-mouse buttons, a clickable scroll wheel, and a DPI settings button just behind the scroll wheel. The mouse features six programmable buttons, which ought to be enough for most gamers. By comparison, the Logitech G502 Wireless ranges from 114 grams to 128 grams with its tunable weight system.
Even with the battery in tow, it’s not a heavy mouse. The Harpoon RGB Wireless weighs a few grams more than the wired version because it must house the battery for wireless mode.
My only complaint is the Harpoon RGB Wireless feels a bit narrow it’s only 2.7 inches wide at its widest point, and I wish it were slightly wider. The sides also have just enough of a concave shape to create a comfy perch for my thumb and side fingers. “It has textured, rubberized side grips to prevent slippage, even when my thumb and fingers got a bit sweaty during a long session.
