The best KVM can hope for is to work and generally go unnoticed. that is not true. Problems I encountered: - The mouse, which I no longer use most of the time. the keyboard is fine - it requires a reboot every now and then when it doesn't even recognize the keyboard, which is made even more inconvenient as it draws power from the attached PCs in addition to the included wall spice, so you'll have to unscrew every connection on the back . It does not come with any of the computer-side cables. Of course it doesn't say that, but it could be said more clearly. Update 2020: The above issues were mostly fixed by replacing the device. It turned out mine had a broken lid. However, mouse movement does not work for Macs over USB. I need a separate mouse connected via PS2 to work on Mac. Also, VGA doesn't work on Mac. I need a separate HDMI cable for my monitor.
