The Goldtouch Numeric Keypad is a convenient, ergonomic solution for users who own a laptop without a full keypad or are simply looking for a more comfortable way to do data entry and make calculations. This numeric keypad powers users through intensive number-crunching sessions. Unlike attached numeric keypads, this one can be easily moved according to the user's convenience, allowing for optimal placement of the mouse as well. It plugs directly into the USB port and casts a low profile. The keypad is compatible with the Mac OS 10.4 and further versions without any additional driver installations.
