Logitech K780 wireless keyboard (E13 Near Plaistow Library)

Logitech keyboard that I've loved for more than a year. Still works fine but some time ago some of the keys started acting up every now and then. I assume it's probably to do with dust or something under the keys, I don't know. Note that the dongle is not included but it works via Bluetooth.

Connects up to 3 devices via Bluetooth or logitech unifying receiver (not included).
