Bests & Worsts Reviews from Amazon

Before ordering this receiver, be very sure that it will work with your devices. I checked the Logitech website before ordering and both my keyboard and mouse are shown as compatible with the unifying receiver. Receiver came, but could not connect either device to it. After a great deal of further searching, finally determined that only certain sub-models of each work and I don't have right sub-models. Seller does not allow this item to be returned.
