Logitech USB Unifying Receiver

Replacement Logitech Unifying receiver 2.4 GHz
ONE RECEIVER – 6 DEVICES
Connect up to 6 compatible keyboards and mice to one computer using a single Unifying receiver – and forget the trouble caused by several USB receivers.
MINIATURE, UNOBTRUSIVE RECEIVER
Our smallest Unifying receiver. It is so small that you can leave it in your laptop, so you don't have to unplug it when moving from place to place.
LOST YOUR UNIFYING RECEIVER?
Use this standalone USB Unifying receiver as a replacement. It is compatible with all Logitech Unifying products (look for the Unifying logo shown on compatible products).
ADDITIONAL RECEIVER FOR LOGITECH EASY-SWITCH
Use an additional Unifying receiver to connect an Easy-Switch mouse or keyboard – or both – to a second computer. Then switch between both computers with the press of a button for truly efficient multitasking. It can also be a great addition to your Logitech Flow setup.
LOGITECH ADVANCED 2.4 GHZ WIRELESS TECHNOLOGY
Advanced 2.4 GHz wireless technology provides a powerful and reliable connection at distances of up to 10 metres, practically without delay or dropouts.
