I bought two of these (one as a spare). No longer need either. This includes main unit, button extension to switch computers, 2 USB cables (the kind that connect to printers), and power cable (to USB). I didn’t have any luck with these switching peripherals, but my work top did have issues powering more than one USB device, but works great and reliably in my experience for switching monitors.
