Great machine
In my opinion this is the best but not "perfect yet" videoke machine, period! Performance wise, 1080p via hdmi, visual-graphics is superb comparable to a desktop or laptop with dedicated GPU.. Audio performance seems to have a built-in Audio DAC to push HD Audio / 3D Realsound. Device software has matured enough for a company who's building it since 1999.. no more "data chips" needed for song volume updates. I initially had issues with initial song updates and firmware update, but after setting up wifi connection to AP solved the issue, using you mobile app to download songs, update the device firmware is a breeze.. No issues seen with the mobile app, connections and or no malware seen by Snort thru packets sniffing/filtering…
