Review on UNNLink HDMI KVM Switch 1080P 60Hz USB 2.0 Switcher with 4 USB Ports - Share Mouse, Keyboard, Monitor, and Printer Between 2 Computers by Robert Mac

There are no problems - it works as expected. Small size. The system's USB and HDMI ports are on the sides, so I bought ultra-thin cables to keep them out of the way. I also use a Logitech Unifying receiver to wirelessly connect to my Logitech mouse and keyboard. depends on the position of the button (up or down) to guess which side is on. You can also connect a USB drive to conveniently transfer files between your systems (the storage is visible to the currently selected system). The device has a 5V socket, but no power supply was included and everything works without it. The accompanying brochure says nothing about external power supply.
