The F keys are incidentally only accessible via the FN key and otherwise with the other function keys (volume up, volume, forward, back and stuff) occupied. The functions of these special keys you can only guess by the way, because they are described nowhere. No middle mouse button for two left mouse button (once under the touchpad and at top left).
A bit annoying is that the right shift key to the right of the "Up" button is located. This often leads to errors. The keys feel at extremely cheap, as if you tap something from the 1-Laden. As a kind of remote control acceptable, regular letter I would therefore not expect me.
UPDATE: Range after a while getting smaller and smaller. New batteries take only about 1 day a little, if at all. Between keyboard and receiver sight, although I have to at ca 1m ran before keystrokes are transferred.
