I just tried it, first few minutes. I didn’t know how to sync it with Xiaomi’s Mi Box S and I asked by phone at the store where I bought it (kontrolakia). For those who don’t know how it syncs (like me), you open the little box (for those who don’t have any remote at all, you unplug it and plug it back in) and then from a distance of 20 centimeters you press the mi button and the circle button at the same time (the middle right and left ones) for 3 seconds.
