Convenient keyboard, plug & play, qualitative: very satisfied! Remarks: 1 - The keyboard is QWERTY (I'm writing with a mini pc android), however, on some hardware, the qwerty is assumed. This problem comes from the PC, the TV, or any other hardware or the mini keyboard is connected. To bearing, for my case, I installed the application "Physical QWERTY keyboard" for android. Other solutions probably exist for other materials. Although the check before purchase.
2 - For best reception, do not hesitate to move the USB receiver away from the TV or other by a USB extension cable: reception interference and receiving distance will be qu'améliorées! (Largely)
