The Manhattan Numeric Wireless Keypad enhances any notebook computing experience and is a game changer when working with important numeric data. The full-size 18-key layout and membrane (full-travel) key-switch technology reduce typing noise, improve response, and provide low-profile keystrokes for fast and accurate data entry. A handy backspace key allows swift corrections. The asynchronous number-lock function allows users to simultaneously input letters from the computer's keyboard and numeric data from the keypad. Its USB wireless receiver connection, plug-and-play installation, and ultra slim, lightweight construction make it easy to pack and travel.
