Summary: Using this, at least as only a monitor switch, requires an AC adapter 9V output to power the box. However, a 9V AC adapter is not included in the package. It works fine after finding a power source for the switch, but it was a bit of an inconvenience to have to go out and purchase an AC adapter because one isn't included.
Summary: Works good theres a few things it don't do. The biggest thing now is I need another switch to print from two computers. The cables that come with this switch would have cost as much as the switch. All in all very happy with my investment.
Summary: Needed a simple 2-computer dual monitor KVM switch and this one works just fine. Comes with all the cables needed: (2 VGA+PS2KM) + (2 VGA) and cable management is about as nice as you could have it. We use the button on the front of the box to switch between computers, but you can also use keyboard commands. We're using 1680x1050 22'' LCD VGA monitors and it looks good. If you want to share a printer, just use the network.
