ONE RECEIVER – 6 DEVICES Connect up to 6 compatible keyboards and mice to one computer with a single Unifying receiver – and forget the hassle of multiple USB receivers. TINY, LEAVE-IN RECEIVER Our smallest Unifying receiver. So tiny that you can leave it in your notebook, so there's no need to unplug it when you move around. LOST YOUR UNIFYING RECEIVER? Use this stand-alone USB Unifying receiver to replace a lost one. It's compatible with all Logitech Unifying products (look for Unifying logo displayed on compatible products) ADDITIONAL RECEIVER FOR LOGITECH DUAL CONNECTIVITY DEVICES Use an extra Unifying receiver to connect a dual connectivity mouse or keyboard – or both – to a second computer. Then switch from one computer to the other with the push of a button for efficient multi-tasking. It can also be a great add on for your Logitech Flow setup. LOGITECH ADVANCED 2.4 GHZ WIRELESS TECHNOLOGY Advanced 2.4 GHz wireless technology provides a powerful, reliable connection up to 10 meters away with virtually no delays or dropouts.
