After reading the reviews, it turned out that the product was exactly as advertised. The direction was clear. Since the hardware on both computers is for PS2, I had to buy a $10 PS2 to USB converter at my local computer store. The converter allows me to take a computer that doesn't have ports for a PS2 mouse or keyboard and plug it into a single USB port. Using KMV Switch worked great. I installed the hardware. Then I started each computer and allowed each to become fully functional before starting the second. When switching from one to the other, the lag time was about 2 seconds or less. Some notice that it can take around 8 seconds between computers. I would recommend that monitor drivers, if any, be downloaded to each computer before connecting to reduce the chance of freezes. In my case I am using a Dell 1703 and I did not use the standard MS plug and play but downloaded the monitor specific drivers.
