With this product, I finally found an affordable and excellent working solution for the operation of two PCs on a set of monitor, keyboard and mouse. Monitor, keyboard and mouse are connected to the switch, rather than with a PC. Then one of two cable strands is connected to each one of two PCs. Switching between the two PCs is quite simple with a short press on the button, which is connected over a sufficiently long cable with the switch. In this solution, I should have come sooner. Gone with the eternal replugging under the desk. Am more than excited and have already recommended this switch my nephew. -> Strong buy recommendation !!!
