So far so good.  I'm using it primarily for internet streaming using the Kodi media center software for windows; watching streaming videos in 1080P and 4K with Dolby Digital and DTS 5.1 audio.  This is a very fast machine for it's size and outperforms comparable android streaming boxes.  So far no buffering issues with 1080P video.  I haven't tried 4K yet.  I'm using a wireless keyboard and mouse.  I would highly recommend this device.
