Review on Parallel 3840×2160P PC Mac Linux Unix by Clinton Delgado

Advantages: Small factor and beautiful design. Cons: 1. This switch only works with the Logitech MK270.2 wireless keyboard/mouse. The switch often stops working with the mouse and the user needs to reconnect the USB drive or cable to the computer.3. Sometimes this switch triggers a kind of parasitic vibration: all the lights flash at the same time and the switch does not work at all. User must completely disconnect all cables to restore operation.4. The LEDs are very bright and do not go out when the computer is turned off. It's a waste of energy and annoying at night. I do not recommend this switch.
