Summary: If you have a BIOS password set for booting, as I do, you'll need to enter it with the keyboard hooked directly to the computer, and then hook it to the KVM. After you've gone through one complete bootup and it installs drivers, you won't have to do this again.
Pros: Impressive little unit. Simple, self-contained, and intuitive--don't really need the manual as ports and cables are labelled with mouse and keyboard symbols. I run 1680 * 1050 and it is crystal clear, no banding or artifact at all. Ports are pass-through; my mouse is a Logitech MX1100 and all features work on both systems: a very nice feature!
Cons: The only potential drawback I see so far is that the cable that connects the switch is really very thin and looks like it could be easily broken.
Summary: Just what I was looking for in the price range I was willing to spend. Works right out of the box and set up in 5 minutes. Keyboard and mouse plugins are USB so it doesn't matter what USB ports you plug them into on your computer. Delays when switching computers is tolerable. around 3-5 seconds to switch keyboard and mouse.
Pros: Easy to hook up, separate button to change computers instead of hotkey, USB instead of PS2 ports, Price (around $20)
Cons: Short wires but worked for me, can't use PS3 mouse without adapter (most, if not all, mice/keyboards are USB these days) about 3-4 second delay from my laptop to desktop but tolerable. Only attached button changer to change keyboard/mouse (other products have both),
Pros: Absolutely love it! I use my monitor to switch the video so I was worried that it wouldn't work without a video signal, as some do, but it works like a charm. There is a single button for switching between the two available inputs which is on a really long cable connecting to the actual device. No need to have the actual unit on your desk unless you want it which is a big plus for me. Horizontal Surface Syndrome is a big issue for me.
Pros: Simple to install Worked instantly Can't get this wrong Due to a lack of additional monitors my wife talked me into getting this, since it was inexpensive, so i can manage our home server. I wasn't too excited about the button on a very thin cord, but i haven't had any problems with this device. Cable length is just fine in my opinion as i had my PC next to our server. The length on the remote cord is long enough to reach around and under my desk to where i wanted it ...
Cons: The noob vision lights that tell you which box your on are annoying, but i am not really one for electronics have as many lights as possible.
Summary: Really this thing is exactly what it is supposed to be, plain and simple. This is definitely a recommended product. And as ALWAYS...
Pros: It took 2 minutes to install everything. Instead of keyboard commands and simple button on a 4' cord swaps machines. It has indicator lights for those who can't tell on machine from the other ( which would bring up a lot of questions, but that's a different review). This thing simply gets the job done and is now helping me keep my desk space open by only needing one mouse and keyboard.
Cons: Doesn't read my brain waves to know if i want to be on my PC or Server. Doesn't make coffee
