At work, I needed to occasionally switch between two computers and was unplugging and re-plugging in the monitor, mouse, and keyboard every time, so I was very happy to find this little gadget! I followed the directions, and it took me about 20 minutes to plug everything into the switch. Ever since then, it has worked perfectly each time I have needed it in the 6 months I have used it. I was a little surprised about how short the cables were, but since my computers are right next to each other and there's a keyboard shortcut to actually switch between them, the shortness has not been a problem.
