Summary: For a budget KVM switch, it works great. Look for a different solution if you plan to use older mechanical keyboards.
Pros: + Cheap compared to other KVM switches. + Works with any PS/2 compatible desktop/laptop. + Comes with SEVERAL cables, they seem to be high-quality. + Does not need external power, runs off the VGA and PS/2 inputs.
Cons: - Unable to power my IBM model M. Some older mechanical keyboards draw more power, and the KVM switch is not drawing enough to power the keyboard. Most other keyboard work fine.
Pros: Computers can detect the mouse and keyboard even if the switch is set to another computer -- most KVM switches don't do that! Hotkeys, and they are NOT software-controlled despite what one review states -- you can switch at any time as long as any PC is turned on. No noticable loss in video quali...
Cons: PS/2 port cutouts are too small -- my keyboard's connector would not fit properly and the connection was wonky at best. I removed the front piece from the unit by taking it apart, and it then worked perfectly because the keyboard could plug in all the way. Cables come out from all sides of the un...
Summary: Occasionally, it would lock up and not respond to commands. A simple power down was sufficient to clear it. But since it was connected to FOUR computers, all had to be powered down (or disconnected) to reboot.
Pros: Inexpensive. Complete with proprietary cables. Has been in use for over three years. Audio switching is a nice convenience.
Cons: Degrades analog video somewhat. More noticeable on high resolution (1280 x 1024). Less noticeable on CRT monitors.
