Summary: The pros for this item is the ease of setup for the novice user, and the ability to switch the audio. The cons are 1) you must use the supplied custom cables - if you are replacing a switch or want to use cables already in place, this is not the switch for you (the custom cables carry keyboard, video, mouse, and audio signals).
Summary: The device doesn't seem to consistently and reliably relay accurate EDID information from the monitor to the Xorg driver, regardless if it is nvidia or intel. Have to resort to explicit modeline configuration.
Summary: My home desk runs up to 4 computers, a home server, a desktop with tv video, a personal laptop, and often a company laptop. I had a two port KVM, but it needed replacing. It wasn't USB and didn't have any audio cables. This 4-port box was delivered 2 day early. Kudos to Tiger Direct! It is pretty and well built, but lives under my desk. More important, it has long sturdy cables that reach all my computers easily, as they are space all over the floor and desk.
Summary: Out of the box I had problems, nothing worked and it hung up again and again. Had to keep rebooting and hooking up an extra monitor just to see what was going on. Seems the NEW keyboard I decided to use with the new switch was defective. Got an old one and everything works fine. Only problem is in getting used to the keystrokes. I had a different switch that used PS2 and a different key combination. The KVM has been working fine since replacing the keyboard.
Summary: It works. But not very well - you need weird keystrokes to go from attached computers - scroll lock scroll lock enter. I only have 2 computers attached, but when I want to go from one to the other, it has to jump thru all ports instead of only to the 2 active ports. It has managed to negatively impact the monitor - as much as I have messed with the settings, the left edge of my screen is off the monitor.
Summary: I have 2 FreeBSD computers, and 2 Linux computers I was try to get it to work with. It did not recognize my Logitech keyboard at all, so I could never get it to switch between ports at all. I tried all of the different key combinations and nothing worked. I tried just plugging in one of the computers at a time and that would work, but that defeats the purpose of the whole thing. The KVM's that have an actual button to switch between ports work every time.
