This is the best box I've used short of the NVidia Shield, and it's pretty well priced too. I was looking for a compact, box with all the essential specs and a customisable Android OS launcher, (many, many other boxes won't even let you change the launcher), It needed to support all the current audio/video standards, and allow for a good amount of future demands, eg. extra USB/SD card expansion. This has all of that, and it pretty smooth in operation.
After a few weeks of daily use, it has meet those needs, albeit when changing resolution (eg. Google TV launcher to Netflix or Disney+) the HDMI signal blanks for a second, which is annoying. I forced the system resolution to match the highest on my TV (4Kx2Kx50fps), and it hasn't caused that issue again since; also, the remote was initially only working as infrared (direct-line-of-sight), but after repairing, it works perfectly via bluetooth. The only other nag is that the 'timber veneer' finish that looks very natural on the varied website image is not veneer at all, but just a printed image on plastic.
