The keyboard works on both Windows (after a short automatic driver installation) as well as in my Android TV stick.
The keyboard is the QWERTY layout, the only surprise is the E and A are not on their accustomed place but in the uppermost row of the numbers (you can see that also in product photos). For me the keyboard is acceptable because it is not used for writing e-mails and other (this is also a bit too small) but movies and series in Netflex to seek and the like.
The keyboard has a built-in battery and can be charged via USB cable. In addition to the mouse pad and the keyboard can be found on the back of another "funny" button. on the front because there are still installed an LED flashlight, although I do not understand the meaning of this little pseudo flashlight but it does not hurt ...
