At first I was sure it was a poor quality KVM switch. so i wired everything up, even used two hdmi-vga cables with suitable usb cables, since my servers in the tower only work with hdmi/dp. wireless keyboard and mouse combo, they work fine, but I've noticed that there are warnings in debian's dmesg, but it still works and only gives warnings on toggling and claims it can't bring back USB. I have to say that at $89 it's worth it. I can't speak for long, but I was immediately impressed, very impressed.
