Review on NEWCARE HDMI KVM Switch: 4K@60Hz, 2x1 HDMI2.0 Ports + 3X USB KVM Ports - Share 2 Computers on UHD Monitor, with Wireless Keyboard and Mouse Support - USB Disk, Printer, USB Camera Compatible by Sheppard Priest

Worked for a while now it just comes off and is very inconsistent. After switching, it continues to behave as if it were detecting a new switch. The screen goes black, the mouse and keyboard turn off, then they all come back and turn off after 1 second. Eventually it seems to stabilize, but it can still randomly act like you've pushed a switch when you haven't. Everything was fine when it worked, but at this price I imagine the quality of the parts and workmanship is just top notch. not so good. You might get lucky, but I suspect there are a lot of lemons in the batch.
