Verified Purchase(What is this?)
This review is from: Konig 2 Port USB 2.0 Switch (Accessory)
I bought this because my wife has a work laptop and we wanted to use same screen and keyboard with that and our home desktop.
This unit was used to switch the keyboard between desktop and laptop. It worked well, powered by the computers it worked even when one was disconnected and also remembered setting.
Note: it doesn't support display switching too (you need a KVM for that) but our monitor has dual input so that was easily done on the monitor.
