Has anyone got this to work?

I can select it in the googles, choose my network with password, it connects, shows on my router, but nothing can find it when I try to cast to it (android and PC). At least I can watch a movie downloaded to the SD card no problem, the sound from the speakers is actually pretty good.

I look forward to trying this when I have a spare moment. Are there any YouTube videos on it?

Maybe it only works with Apple devices?!? I can't find any other info about it.
