Bests & Worsts Reviews from Amazon

This switch simply works. No complicated setup, no software to install. Just turn off both computers. Plug the shared keyboard, monitor, mouse, speakers and microphone into the switch, connect the included cables into the switch and the two computers. Then turn on the first computer, the one you want to designate as #1. After the first computer boots up and everything is okay, then push the #2 button and boot the second computer. That's it. From then on, you just push the button #1 or #2 to make the switch. It switches instantly, if both computers are not asleep. If one is asleep, it gives the signal, and then the PC takes only a few seconds to wake up. I read a lot of reviews and I'm glad I did. Other switches seem to need software to work well, and rely on keystrokes to change. Because this switch has a button, it just truly switches over without any need to install software, making it the most generic. For PCs, you can use the scroll-lock+scroll-lock key combination to elicit the switchover. But it's simpler just to teach my kids to select button 1 or button 2.
