Decent speed processor and RAM to start with and a joy to use 7 months ago. Now WIFI antenna broken and dangled. Sound port makes output sound like garbage on Zoom calls.  LED red light no longer turns blue when connected to HDMI source. Flashed blue for a brief second and stayed red forever. Nothing can be seen on the display monitor. Replaced the HDMI cables to no avail. No US telephone number to troubleshoot. NOT a good buy over all.
