As soon as i saw its running Android, I knew it's dead in the water since google never purchased the licenses needed for HD audio codecs. Aka no DTS hd pass through.
It's made in China for China market (big hint is tf card support)
Nothing to see here, move along.
Gene, I had pretty good experience with Amazon fire stick. It also running customized android and suffers from same limitations, but it does have few strong pros:
Pretty stable, easy and regular updates. I originally used it with Kodi, but quickly switch to much easier Plex.
In fact i could probably write few pages about how awesome it is.
In many aspects it is as good as Kaleidescope was.
