1 out of 5 eggsBuyer Beware

Pros: None - Switch does not work!

Cons: This switch does not work. The technical support is just as bad as the switch. They cannot even get the correct model number in their email responses. To add insult to injury they will charge a $24.75 restocking fee plus shipping costs to return this defective item

2 out of 5 eggsFlakey keyboard support

Pros: When it works, it works great. The picture quality does not seem to suffer at 1920x1200, the keyboard commands are quick and easy. All the cables were included.

Cons: Does not work well with Linux (requires cycling the keyboard on boot). Latest firmware is rubbish.

Other Thoughts: Do not install the latest firmware!

I used this for about two years and had to deal with unplugging/plugging in my keyboard every time I booted a linux box attached to the kvm. If linux booted, the kvm would completely disconnect the keyboard (hotkeys would not even work/no power lights). I recently bought a new mouse and that required I do a combination of unplugging both and plugging them back in in a certain order. I checked if there was new firmware and there was. Installed it and now I can only get the keyboard to work (even with just Windows) about 1 in 100 tries. It is completely random on how to get it to work as well. Sometimes a power cycle, sometimes unplugging/plugging the keyboard, sometimes with a mouse, sometimes without. It can take 30 minutes to get the keyboard to work with it.

5 out of 5 eggsVery Professional KVM

Pros: This is by far the best USB KVM I've ever used. Many others I've used in the past have all been quirky, but this one pretty much works flawlessly.

Cons: Out of the box, some of the "extra" buttons on some mice might not pass through to the PC. However, the KVM can be easily configured to use a non-emulating mouse mode, which allows full functionality.

2 out of 5 eggs

Pros: hasn't exploded yet.

Cons: Won't accept my Corsair keyboard, won't switch peripherals when a computer goes offline, wireless mice are hit and miss. Have to power it down regularly to even get it to function. Too expensive for something that doesn't work.

Other Thoughts: Don't bother buying this thing. I've been trying to get it to function somehow since day one. Finally switching back to my 2 port kvm, since 2 computers is better than none.

3 out of 5 eggsPower on problems

Pros: Low price, nice cable sets, solid construction, no problems with video

Cons: I leave the switch on 24/7 but often shut-down one or more computers connected to the switch and when systems are restarted the switch usually does not recongnize the mouse. Have to unplug/plug mouse, doesn't matter if wired or wireless mouse. Also have updated firmware to latest version (as of 11/01/2012) and that did not resolve issue.

5 out of 5 eggsBig improvement over old KVM

Pros: It supports my hi-res monitor. Previous KVM was a Black Box KV824A. It did not have DVI ports and what it did have did not support my Samsung 2343 2048x1152 monitor. The screen images were always a bit fuzzy. With the Aten, everything is tack sharp. Came with full set of cables including audio pink and green.

Cons: A bit expensive, but my eyes are happy now.

2 out of 5 eggsNot compatible with Linux for me.

Pros: Good quality and solid construction. Cables provided were very nice.
Worked as advertised with my Windows 7 machine.

Cons: I purchased this KVM because it listed it was compatible with Linux. However I have three Linux machines that all displayed the same behavior while the unit was in place:
The Keyboard does not function.

Mouse worked, video looked good. I was unable to type in a user name and password. Remove the KVM switch from the equation and everything worked like normal.

Other Thoughts: Was not able to consistently get into BIOS or Quick Boot menu by pressing "DEL" key or "F8" key while KVM was installed. Sometimes it worked, but mostly it did not, again this does not work for me as most of my machines have multiple hard drives with different operating systems to choose from while booting from the quick boot menu.

4 out of 5 eggsgood switch

Pros: Unbeatable DVI quality @ 1920 with zero lag. Yes, you can run the most visually-demanding games with this switch and see virtually every frame as if you were connected directly.
Solid, heavy construction.

Cons: hardware compatibility.

**DO NOT** even think about buying this switch if you intend on connecting it to *anything* that uses a standard 15-pin analog video connector DESPITE what the description on Newegg states. The outputs/inputs on the switch are DVI-only and no number of adapters or jerry-rigging (short of a solution that involves soldering) will allow an analog signal of any kind.

While this switch has an absolutely flawless 1920 signal, **IF YOU ARE A GAMER** and your game requires the use of more than 2 mouse buttons (or you're like me and have become fond of using the mouse wheel button as a "double-click" alternative), you will be completely out of luck with this switch.

Other Thoughts: Wish I had paid attention to other reviews regarding analog. For the money, I could have picked up something else that supported more hardware. Good device overall, but would not be my first choice given a redo.

4 out of 5 eggs

Pros: Easy to setup and get working and easy to use once you get it setup. It has a small footprint so will fit on your desk without too much problem. It comes with all the cables you will need to connect 4 DVI-enabled computers. The switchbox and cables seem to be quality made.

Cons: Cables are a bit short and are rather stiff, but they work. Sometimes you have to hit the switch twice to get it to change to the computer you want to be active. I wish it had a power on/off switch on it.

Other Thoughts: I have it configured with an older Dell Dimension (XPS), new Dell XPS, and an HP docking station with an HP laptop. The switch box sits on my desktop and I use the switches on the box to change between computers instead of the mouse or keyboard hot keys. I would definitely consider buying another one of these and would recommend it to others.
