Active mouse
Very practical mouse, with good battery life thanks to the mouse usage options. With the logitech HUB, you can insert macros, which is handy for changing desktops on Windows. I use it for my desktop and my laptop. So I keep the dongle on the desktop, and use the mouse's wifi. And for the laptop I use Bluetooth. It's really handy, because I don't have to remove the dongle afterwards... Goodbye to forgetting things... Or rather, hello!
