Want to wirelessly connect a Logitech Flow or Easy-Switch mouse to a second computer? Simply add an extra Unifying receiver and plug it into your second computer. Then use a Logitech Flow mouse to seamlessly cut, paste and move files between computers. With Flow technology, the cursor automatically crosses from one screen to the next. Or use an Easy-Switch mouse to switch from one computer to the other with the push of a button. Either way, the tiny Logitech Unifying receiver stays in your computer so your wireless mouse is always connected and ready to use. And it connects up to six Unifying devices to your computer so you can easily add a compatible mouse or keyboard – without sacrificing precious USB ports. Advanced 2.4 GHz wireless technology provides a powerful, reliable connection up to 33 feet (10 meters) away with virtually no delays or dropouts.
