I am happy with this product when it comes to using it on my Samsung Galaxy S6 and S9 but I have found that it is not Works with the nVidia Media Box Shield (aka Android TV) (slowly responding, repeatedly pressing, or intermittently not responding). For mobile I would say this keyboard is excellent value for money. If the intended use is for a media box I would suggest using a different model. As for other supported devices (iOS and Windows devices), I can't speak for those who see I haven't tested the keyboard on them yet.
