Manufacturer description
The Razer Viper Ultralight is a wired, ambidextrous gaming mouse built for players who want a light, symmetrical shape that works in either hand. At 71g, it keeps weight low for fast flicks and long sessions without needing a drilled honeycomb shell. This listing is the Mercury White colorway. Clicks run through Razer's 2nd generation optical mouse switches. They register a press when a light beam is interrupted instead of waiting for a metal contact to close. Tracking comes from Razer's 5G optical sensor. The Speedflex cable is designed to cut drag, so the wired connection gets in your way…
