The Razer Diamondback is a legendary mouse for a niche audience, those who reject the short, fat gaming mice that now dominate the market. It debuted in 2004, and its long, thin body and ambidextrous grip made it perfect for those with a claw grip and love to lift and move their mice. After laying dormant for a few years Razer has brought it back, imbuing the mouse with the company's Chroma LED styling. But the new Diamondback has some very big (and very specific) shoes to fill.
