The Wired USB Mouse for Life features a three-button/scroll wheel setup that offers silent clicking when you need to get work done and don’t want to disturb anyone in a quiet environment. A high-definition optical sensor provides reliable and responsive control when you’re navigating and the comfortable, contoured shaping feels great for either right-handed or left-handed users. It offers Plug & Play installation with a standard USB wired connection and is built to last with a 5-year limited warranty.
