USB plug and play optical mouse with built in numeric keypad. Two devices in one means less peripherals to carry. No more "hunting and pecking" for number keys on Notebook Computers.
very useful gadget4/6/2007
I bought this item to use with my destop at work because I wanted to minimize moving my hand from the mouse to the keyboard. Entering number data is a breeze now while you still have your hand on the mouse. I also use it with Macroexpress to assign macros to each of the keypad keys. Installation was fast and easy and the quality of the optical mouse is great.
