This KVM is fine, IOGear makes pretty good products. I am writing this just to provide a few comparison notes on the few but important differences between this and its slightly more mature sibling the GCS632U. 1) This KVM does not offer any keyboard shortcut. There is a little wired "remote" connected to the KVM, and you must click the button when you want to change from one machine to the next. This does not seem ideal to me, because your hands must leave the keyboard and I would worry about the clicky switch failing over time. The GCS632U offers a typical "double scrolllock tap" to change over, and this can be changed to another keypress as desired. I find this works much better than this units remote button setup. 2) This KVM has cables that connect to the monitor port and TWO USB ports on each target computer. The GCS632U oneups this in a neat trick it combines the keyboard and mouse inputs into ONE USB cable, so it only takes up ONE USB port on each target computer. Very nice, and fewer cables to plug in. This feature alone is actually enough for me to return the GCS22U for the upgraded GCS632U. 3) Last, but not least, the GCS632U adds 18" plugs for audio. I personally dont use this, but for those who want to connect a single pc speaker system (or other audio output) to the two target computers, this is a nice feature. Hope thats helpful. To me, an extra $10 is worth having an extra USB port free on my laptop and other computer! And I much prefer the keyboard shortcut vs the remote button! http://garyadair.com/326191
