REVIEWS:
1) Works as advertised: Great product!

Here is an FYI that may help someone else.

The initial install worked great but when I rebooted my second computer the system repeatedly hung at reboot. After some investigation I found that the hangup was occurring during the POST process of the BIOS boot. The problem seems to be related to keyboard output during BIOS boot. The solution, in my case, is to make sure that the KVM switch is selected for a computer OTHER than the one I am currently booting.
2) Great Product: Are you looking for great KVM without spending a whole lot? This is the one for you!
3) Could Not get to work: I was excited when I received the unit and thought it was great that it included cables, however I had to return the unit. It would never recognize my keybooard on just the first PC. I tried it on 2 PC,s and technical support had no suggestions, other than it should work plug-and-play. I"m still looking for a replacement.
4) Easy to set up and works great!: Easy to set up...just follow the directions. I had seen some reviews that said there were problems with wireless keyboard and mouse, but I had no problems. Plugged the wireless connector into the keyboard port, and since I use a trackball, plugged it into the mouse port. Amazingly, the wireless mouse also works...a bonus.
5) Works great with Windows and Mac: I"ve had mine for about a week now, and it"s working great. Does exactly what it says... switches smoothly between computers. With Windows, switching is a bit slow because it takes a couple of seconds for Windows to recognize the usb devices each time. It"s a lot faster with my Mac... switching is almost instant.

My only complaint is the physical design. When connected to 4 computers, the cables are sticking out all four sides. This makes this huge glob of cables, and makes it almost impossible to set on my desk. It would have been nice if all the cables plugged into one side. For this reason, it gets 4 of 5 stars.
