Hexus posted a review on the Corsair Harpoon RGB
A quote from the article:
A sub-£30 optical mouse for gamers on a budget. The great thing about PC gaming hardware is that there's so much choice. You aren't restricted to certain peripherals, and there literally is a keyboard or mouse to suit every individual. The only thing you need to be wary of is cost, as while the entry point tends to be low, prices can spiral out of control for high-end equipment that casual users aren't likely to need.Corsair Harpoon RGB Review @ Hexus
When it comes to gaming mice, the likes of the Asus RoG Spatha and Fnatic Gear Clutch look tempting if you're willing to splash large amounts of cash, but if cost is a key consideration, Corsair reckons it has a noteworthy alternative in the form of the Harpoon RGB.
