Very good, reliable mice. I couldn't see it posted elsewhere.
"Logitech Wireless Mouse M215 gives you the comfortable, intuitive control you want for your notebook. Place your wireless mouse wherever it feels best and forget about performing tricky finger manoeuvres in a fixed location like you do with a touchpad. Instead, you'll enjoy smooth, precise tracking, easy text selection and effortless scrolling. There's no complicated setup or software to install. The nano-receiver is so small you can plug it in once and forget it. The Logitech Advanced 2.4 GHz wireless connection is reliable and powerful. And the included Duracell AA and intelligent battery management features give you enough power to go for months before your first battery change."
