Advanced 2.4 GHz wireless technology provides a powerful, reliable connection up to 33 feet (10 meters) away with virtually no delays or dropouts. It's so tiny you can leave it in your notebook, with no need to unplug it when you move around. Use it to replace a lost receiver or extend a Logitech Flow setup. Compatible with Windows and macOS.
