The Low-Force Numeric Keypad is perfect for narrow keyboards or in conjunction with your laptop. Use it in any situation where a stand-alone keypad is preferred as it allows users flexibility in positioning the keypad to the right or left of the keyboard. The integrated 2-port USB hub enables you to easily connect other input devices such as mice without having to access USB ports on your computer. Low force, tactile mechanical key switches add to both comfort and operating life. (Designed in collaboration with the world's premium switch manufacturer.) The Numeric Keypad connects to any available USB port on your computer and is compatible with virtually any USB capable operating system. No special drivers are required.
