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.
Pros: Simple setup, small, performed as expected for a year or so
Cons: Randomly "blanks" out - makes a beeping noise, and the video on the attached screen goes blank for 10-15 seconds at a time, several times a day. Randomly "blanks" out the keyboard and mouse as well. Contacted support and received little assistance.
Summary: I just stuck it on the side of the desk with gorilla velcro! Fortunately the hot keys work so well that I have not had to actually access the switch unit so I could have dumped in the floor behind one of the PCs. I am using this on PCs from an old AMD K6-400, two Athlon XPs and a Core2 Duo.
Pros: It works and works well. Just follow the instructions and so far not miss yet. Best of all the time delay is generous so even if you hestitate for some reason on the hot key sequence, it will usually be waiting for you. The sound switching works and the sound is as clear as unswitched.
Cons: The only one is the usual; the cables are attached on all 4 sides making it impossible to neatly put it anywhere!
