Wireless Mouse that was born to perform. The Manhattan Performance Wireless Optical Mouse II combines modern design with advanced precision and performance. Its top-mount push button instantly shifts resolution from 800 to 1200 to 1600 dpi to suit a wide range of applications, including routine computing tasks or computer games and editing requiring a fine touch. Its full-sized shape and four-button configuration provide direct access to essential commands with minimal wrist movement. A non-slip texture applied to critical surfaces helps provide a secure, comfortable grip. The remarkably small yet powerful USB micro receiver with 2.4 GHz technology provides an effective range up to 10 m (33 ft.) and stores in a special on-board compartment or remains installed for true wireless convenience. Included auto power management helps maintain proper battery levels for long, reliable operation.
