The new Logitech MX Master 4 mouse succeeds the Master 3 and 3s, offering a premium, ergonomic experience for both professional and regular users. It features design tweaks with a less matte, more durable hard plastic finish, and is slightly heavier than its predecessor. A key upgrade is its significantly quieter buttons, which provide tactile feedback without audible clicks, a feature that may appeal to some users seeking a less noisy input device.
