Review on Macally Bluetooth Number Pad and Mouse for Laptop Combo - Rechargeable Wireless Numeric Keypad and Slim 10 Key for Mac and Windows with Portable Laptop Mouse Set by Michael Vargas

I bought it refurbished or refurbished so there were no instructions for the mouse. You'll need to hold down the left and right mouse buttons (or try other key combinations I think) for the pairing to begin. The keyboard will be paired after you hold down the Enter and Backspace keys. I'm using a Linux computer with a pluggable bluetooth dongle. Works perfectly.
