Review on 💻 Targus Ultra Mini USB Keypad: Efficient Plug-and-Play Device with USB Port Connectors - Compatible with Laptops, Desktops, and More! by Heather Laudun

Bought this for my wife (maths teacher). She uses it to enter notes and the like. This is the second one we have. The dog ate the first one. Works with both laptops. Just plug and play on Windows XP and Windows 7. We haven't tried this on our Windows 8 laptop but I'd be surprised if there was a problem. Good enough for everyday use. Not too heavy and doesn't seem to mind dropping from her lap to the floor from time to time. Inexpensive enough that you won't cry when it's time to replace it.
