Does the job (very well)
Use to share keyboard/mouse between 2 PCs, switch from one to the other without a hitch thanks to the button on the wired remote control, no loss of connection when switching from one to the other. You can also share a USB key between the 2, great! No need to connect an external power supply, it just works! Note that 2 USB A/B cables are supplied, which is not specified in the description.
