Compact keyboard (almost too): the "Input" and "Shift" keys would be more enjoyable if they were bigger. Touch keyboard without problems. Has automatically connected to a pre-existing Unify receiver (the mouse). The three alternative covers of different colors (white, blue or purple) for the battery are 100% gadget and are not very "rich". Very good price / quality ratio for this, however we can say after two short weeks of use. Purchase and delivery without pb, as usual with Amazon.
